The New York senator may have pushed a little too hard too soon with some donors - helping them realize why Obama is a better candidate in the first place:
There's a fine line between confidence and arrogance, and for some fund-raisers the Clinton team crossed it. "They clearly communicated a message that this candidacy is inevitable because we'll have more experienced consultants, more political insiders, more money and more of every resource that is vital to being nominated," says a prominent New York donor who joined the Obama camp but declined to be named to protect friendships with Clinton supporters. "Therefore, you are politically stupid if you don't get it, if you can't add."
Sounds like her.
