It's been relatively quiet on the super delegate front this week. On Wednesday, Obama gained a super from Connecticut as the state named its add-on delegate. That was negated yesterday as Rep. Al Wynn resigned Thursday. If Gov. O'Malley schedules a special election to fill that seat before the convention, then Donna Edwards would add that delegate back onto Obama's column, but there's no guarantee of that. It's at O'Malley's discretion at this point.
Puerto Rico's governor was indicted yesterday as well, and assuming this forces him out of office (which you'd think it would), that's another Obama super out the window.
But today, Sen. Bob Casey endorsed Obama.
"The endorsement comes as something of a surprise," Dan Pfeiffer, Obama deputy communications director, said in a statement. "Casey ... had been adamant about remaining neutral until after the April 22 primary. He said he wanted to help unify the party."
"Obama strategists hope Casey can help their candidate make inroads with the white working-class men who are often referred to as 'Casey Democrats,'" Pfeiffer said, adding that the group is liberal on economic issues, supportive of gun rights and opposed to abortion.
I still believe very strongly that the only endorsements really worth much (beyond a day of positive media) are those of mayors with functioning patronage machines, so I wouldn't expect Casey's endorsement to be worth much in the polls. But, he is a super delegate, and in a race where every delegate clearly matters, and in which super delegate momentum might pay dividends for the remaining undecided supers, Casey's endorsement has worth beyond his electoral muscle.
On the pledged delegate count, the big news will be Texas' county conventions, where we will finally get definitive and official word on who won the Texas delegate race. Burnt Orange Report will have full coverage.
