WASHINGTON (CNN) - While Sen. Hillary Clinton was endorsing Sen. Barack Obama, some of those weighing in on her campaign Web site were less willing to concede.
As Clinton wrapped up her remarks Saturday in Washington with a plea for supporters to work "as hard for Barack Obama as you have for me," many were posting messages saying they would never vote for the presumptive Democratic nominee. A few even called on her backers to visit Sen. John McCain's campaign Web site.
"I love her and will vote for her in 2012, but it's McCain all the way now," wrote one within moments of the former first lady's address.
Whether that sort of statement signals a defection to the presumptive Republican nominee, a voter less likely to make it to the polls on Election Day or just a bit of low-grade, post-primary grumbling - it's the sort of sentiment that makes for a nagging, low-grade anxiety among nervous Democrats and brings a gleam to the eye of McCain.
As Democratic leaders met last month and decided to seat Florida and Michigan at half strength at the convention, angry Clinton supporters who had backed her plea for the seating of full delegations from both states began to chant, "Let's go, McCain!"
And as Clinton's presidential bid wound down, some of her loudest supporters began insisting they would consider voting for McCain if she were not the Democratic nominee.
