Superdelegate fun

George McGovern went on MSNBC to publicly switch from Clinton to Obama. He has been a long term Clinton supporter.

On the other side, NC Rep and superdelegate Heath Shuler actually pledged to Clinton today. (His district went for Clinton.)

Also, Obama is heading to DC to meet with undecided superdelegates tomorrow. (Clinton is meeting with some today.)

LATER: (AP) Obama has picked up four more superdelegates today including a second who has flipped from Clinton to Obama.

And, (TheHill) Sen. Feinstein "will ask the former first lady to detail her plans for the rest of the Democratic primary." (Sounds like the beginning of a flip.)

Later Still: Clinton picks up an Indiana superdelegate who also cites his district's voting as his reason.
