Don’t call it a comeback? A new USA Today/Gallup poll finds Clinton and Obama virtually tied in a national poll, 37%-36%. “Mark Penn, Clinton’s chief strategist, calls the USA TODAY poll ‘an outlier’ that is ‘completely out of sync’ with other surveys. He says it is ‘seriously flawed’ for including so many independents unlikely to vote in Democratic primaries…Among Democrats alone, Clinton leads Obama by 5 points, 34%-29%…Among independents, Obama leads by 9 points, 31%-22%.” Good to hear, but admittedly this poll doesn’t sound quite right: “An ABC News/Washington Post poll taken last Tuesday through Friday gave Clinton a 12-point lead.” Update: Iowa’s all tied up too: Clinton 25%, Edwards 23%, Obama 22%. “Women have a strong preference for Clinton, while those under the age of 45 give Obama a double-digit lead. Obama and Clinton are nearly tied for support among first-time caucus-goers, but previous attendees give Edwards a narrow edge over Clinton.”
