Ah, our political values at work:

[A] study by the Center for Responsive Politics concludes that campaign contributions have become a fairly reliable predictor of whose side a superdelegate will take.

And if that’s the case, it’s good news for Obama. Since 2005, his PAC has donated $710,900 to superdelegates, more than three times as much as Clinton’s PAC has. Her PAC distributed $236,100 to superdelegates during the three-year period.

The study found that the presidential candidate who gave more money to the superdelegates received their endorsements 82 percent of the time. That’s based on a review of elected officials who are serving as superdelegates and who’d endorsed a candidate as of Feb. 25.

Just one of many reason I’m much more careful with my political giving than I used to be.  I don’t give money to buy votes, even for candidates I’m otherwise supporting.
