Brit Hume just mentioned this site:

It constantly updates the odds of victory for both Donald Trump and Hillary Clinton.

Currently:
HILLARY: 65.1%
TRUMP: 31.5%

It still favors Frau Hitlery, but only because she begins with 240 guaranteed electoral votes, in states dominated by Democrat zombies who will vote for her no matter what. Even if Trump has growing momentum, that's a tough handicap to overcome for Trump.
