Well... since then... she's switched again.
When she switched, the Obama campaign made a video that got lots of play, not only on YouTube, but also on cable news programs.
"It got more hits than Paris Hilton and Britney Spears. It got the all-time highest over that weekend," Klopfer said of the video's YouTube hits. The video was so potent that the Clinton campaign made an answering video with its own former Obama supporters.
But when Klopfer showed up at a John Edwards house party this morning, it was because she was on the verge of switching again.
"In both of those people I didn't see the experience that I'd like to see and kind of the groundedness that I'd like to see," she said of Obama and Clinton, "so I'm really looking at Edwards, and I'm still really looking at (Bill) Richardson."
Klopfer said she went to see Richardson last night in Mount Pleasant last night and was impressed by him.
"Probably I'll caucus for Richardson," she said after Edwards spoke. "My guess is he won't be viable, and then I'll probably scoot right over to Edwards."
In MSNBC's First Read, she's getting pilloried in the comments section for her switch. MSNBC had more about this yesterday morning, and Keith Olbermann also mentioned her at the top of his broadcast last night.
