“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.“
