Hillary Clinton - 1.3 million
Jeb Bush - .26 million
Donald Trump - 3.7 million

No, I don't think that Donald Trump is the runaway favorite for president. On the other hand, a look at these would make Walker's collapse and Bush's struggles (despite a goliath $100 million warchest) less of a surprise than the political press has portrayed. Likewise, Sanders' challenge to Clinton would be less surprising.
Bush is the real surprise to me. Endorsements and dollars show that he's the establishment's pick, but people just aren't interested in the guy. It would be kind of amazing if someone went from having a D-list celebrity following to sitting in the oval office in a little over a year.
