100 million bucks is quite a chunk to lose. Can't blame 'em for getting sore about that.
If they're honest, they'll blame themselves. George W. Bush had an extremely loyal base, but they felt double-crossed by his anti-American policies, e.g. refusing to secure the Mexican Border.
His photo-ops with the Clintons didn't help.
Neither did Barbara's snide comments about Sarah Palin.
George P. Bush got embarrassingly shellacked in Texas. You would think that W and the rest of them would get the message.
