Labor and Supers Swell the Ranks.

‘Sen. Obama will fight for better wages, real health care reform, stronger retirement security, fair trade and an end to the outsourcing of good jobs,’ said Hoffa. ‘He understands the importance of giving workers a voice at work and will fight for strong unions to help rebuild America’s middle class.’” The Teamsters, 1.4 million strong, back Barack Obama, as does the 65,000-member International Brotherhood of Boilermakers. (The Change to Win labor consortium may follow suit tomorrow, although four of its seven member unions already back the Senator.) Meanwhile, Sen. Obama picked up four more superdelegates today: Ron Kind of WI (who said he’d follow his district), Lloyd Doggett of TX, and Dana Redd and Donald Norcross of NJ. (Redd had previously backed Clinton, meaning today’s superdelegate swing was 5.) Update: Change to Win backs Obama, although the three unions not already supporting the Senator abstained from voting: “[T]he three unions released the federation to work for Obama in the upcoming primaries and caucuses.

MAD for Obama.

“The Mexican American Democrats believe that Senator Obama’s experience bringing Americans of all ages, religions, races and ethnicities together make him the best candidate to make progress on the issues that matter to Hispanics in Texas and across America. Obama’s leadership in the U.S. Senate on comprehensive immigration reform and his specific plans to strengthen our schools, bring about universal healthcare, and provide tax relief for working families show us that he is truly committed to improving the lives of Hispanics and all Americans.” Sen. Obama receives the endorsement of the Mexican American Democrats of Texas, the state’s oldest Hispanic political organization.

Houston, we have a liftoff.

The Houston Chronicle endorses Sen. Obama: “Of the two finalists for the Democratic presidential nomination, the Chronicle believes Sen. Barack Obama of Illinois is best-qualified by life experience, skill and temperament to be the standard bearer for his party…The passion and excitement that Obama has brought to the race can only stimulate more citizens to participate in the electoral process. The Chronicle urges Texas Democrats to cast what could be decisive ballots for his presidential nomination.

The Clinton Spin gets Even Dumber.

As the Clinton campaign begins pulling out all the stops in Wisconsin, Mark Penn, he of the “impressionable elites” and “insignificant states,” offers up another doozy: “Winning Democratic primaries is not a qualification or a sign of who can win the general election. If it were, every nominee would win because every nominee wins Democratic primaries.” So…winning primaries is not a good way to pick a candidate now. Can we still get Mike Gravel as our standard-bearer, then?

For his part, Clinton adviser and superdelegate Harold Ickes (son of the prominent progressive and New Dealer) at least conceded the importance of winning, although he too is putting his faith on a bailout by the supers (and/or a successful joint pincer movement with McCain.) According to him, the campaign will go until June, whereupon supers will flock to Clinton. “‘At or about – certainly, shortly after – the seventh of June, Hillary’s going to nail down this nomination,’ Ickes said. ‘She’s going to have a majority of the delegates.’” Sorry, not bloody likely. (About that June 7 match-up, tho, Sen. Obama recently picked up the endorsement of Puerto Rico Governor Anibal Acevedo-Vila, so even that final Clinton firewall looks to be suffering from a few cracks.)

The Heads Convene.

“At a private dinner that Mr. Edwards, a former senator, held at his home last Saturday for a dozen close friends, he said he had spoken recently with Mr. Gore about the benefits of neutrality, someone who was at the dinner said…Mr. Edwards said he intended to remain on the fence for the time being, the person said.” It looks possible no more major endorsements will be in the offing for either Democratic candidate. Perhaps noticing the daunting math that faces Sen. Clinton’s campaign, the big undeclared Dems seem to be envisioning themselves instead as much-needed brokers of the peace. “A number of senior Democrats, including Speaker Nancy Pelosi and three candidates who have dropped out of the 2008 race, former Senator John Edwards and Senators Christopher J. Dodd and Joseph R. Biden Jr., have spoken with Mr. Gore in recent days. None have endorsed a candidate, although Ms. Pelosi made comments on Friday that were widely seen as supportive of Mr. Obama when it came to the process the party should use to make its choice of candidate.

Milwaukee’s Best.

The Obama campaign has been derisively and incorrectly described as more rock tour than political campaign and his supporters as more starry-eyed groupies than thoughtful voters. If detractors in either party want to continue characterizing the Obama campaign this way, they will have seriously underestimated both the electorate’s hunger for meaningful change in how the nation is governed and the candidate himself. In an interview with the Milwaukee Journal Sentinel Editorial Board on Wednesday, the first-term senator proved himself adept at detail and vision. They are not mutually exclusive.” The Milwaukee Journal-Sentinel endorses Obama for president.

UFCW for Obama. SEIU next?

“Senator Obama understands the needs of working people. As a community organizer, he understands that America must restore the balance between working America and corporate America. He will fight to level the playing field on behalf of workers across our country. He will fight to regain the rights and protections workers have lost after too many years of the Bush Administration.” Sen. Obama picks up some key labor endorsements. First up, the United Food and Commercial Workers International Union, which is 1.3 million members strong and “has a powerful presence and a strong organization in key primary states such as Wisconsin, Hawaii, Texas and Ohio.” And, though it hasn’t been announced for sure yet, Politico‘s Ben Smith says an SEIU endorsement is imminent. “‘It’s done,’ said one person close to the union.” Let’s hope so — we’ll know tomorrow.

Also, we should probably expect Bill Clinton to dust off the union-busting rhetoric.

Update: SEIU endorses. “‘There has never been a fight in Illinois or a fight in the nation where our members have not asked Barack Obama for assistance and he has not done everything he could to help us,’ Andy Stern, the union’s president, told reporters in announcing the decision.

The Hightower Cavalry.

“‘The Obama campaign is a phenomenon,’ says Hightower, who will make his formal endorsement soon but spoke this week with Laura Flanders and this writer on Radio Nation. ‘Í am impressed with the tone of his campaign and, most of all, I am impressed with the people who have surged behind his campaign –- especially the young people,’ the Texan says of Obama.” Well-known Texas populist Jim Hightower gets set to back Barack Obama.

Speaking of much-loved Texas populists: Alas, the late Molly Ivins is no longer with us. But, she made her own feelings pretty clear back in the day: “I’d like to make it clear to the people who run the Democratic Party that I will not support Hillary Clinton for president.

The Trickle of the Supers…

I posted earlier today on superdelegate Christine Samuels switching from Clinton to Obama. Now, according to the AP, it seems Clinton may be losing a few more: Based on his district’s overwhelming support for the Senator from Illinois, Rep. David Scott (D-GA) has switched to Clinton from Obama, and “two other superdelegates, Sophie Masloff of Pennsylvania and Nancy Larson of Minnesota, are uncommitted, having dropped their earlier endorsements of Clinton.” And, perhaps buttressing TNR’s recent argument that Clinton’s support among Black establishment figures is wavering, none other than Rep. John Lewis goes on record about a possible switch: “‘It could (happen). There’s no question about it. It could happen with a lot of people…we can count and we see the clock,’ he said.” (Which reminds me: A good place to keep track of superdelegate shifts, if you haven’t found it yet, is DemConWatch.)

Update: It’s official. John Lewis switches to Obama. “‘In recent days, there is a sense of movement and a sense of spirit,’ said Mr. Lewis, a Georgia Democrat who endorsed Mrs. Clinton last fall. ‘Something is happening in America and people are prepared and ready to make that great leap…’I’ve been very impressed with the campaign of Senator Obama,’ Mr. Lewis said. ‘He’s getting better and better every single day.’Update 2: Or did he? Now, everyone’s confused.

The Last Dog…is feeling poorly.

“What we are seeing is way beyond historical or transformational. The human mind cannot get around what is happening in politics.” James Carville (my former employer) goes on the record about election 2008, and Clinton’s prospects going forward. “She’s behind. Make no mistake. If she loses either Texas or Ohio, this thing is done.” (What he didn’t say: if Clinton doesn’t win Texas and Ohio by large margins, this thing is also done. Given the delegate situation, a tie goes to Obama.)

In related news, another 1992 Clinton campaign head, David Wilhelm, jumps ship to Obama. “He said in a conference call today that Mr. Obama was more electable than Senator Hillary Clinton. Mr. Obama’s campaign is evidence of his leadership, he said, calling it ‘masterful.’ ‘He has out-worked her, out-organized her and out-raised her,’ Mr. Wilhelm said. ‘I know organizational excellence when I see it, and the Obama campaign, win or lose, will serve as a model’ of execution of strategy, message discipline, application of new technology and small-donor fund raising.” Happily, Wilhelm is also a resident of Ohio, a former DNC head and a superdelegate.
