The defections from her campaign appear to be more about their 'fair weather friends' than a disrespect for her solidity.
If she had had more money up front, I believe most of them would not have left.
Actually, she is better off without them.
In my brief exposures to national politics, one constant was the total lack of convictions and beliefs of the vast majority of those who work political campaigns. They are in it for themselves, and hope that by hitching onto some candidates star they will propel themselves to great wealth, power, and fame. And for not a few, it works. Think Stephanopoulous, Gergen, Rollins, Jody Powell, Dick Morris, Beckel - all people without principles who will switch their loyalties in a heartbeat if it will improve their status or income.
