Simple math. If you get 30% of 100 new votes then the other guy gets 70%. Not a good deal. As you point out the election was close. It won't take that many more Latino votes to regulate the republicans to the dustbin of history. Think about it, the republicans sure aren't.

You may be right, but consider his experience in Texas:
"Meanwhile, in Texas Gov. George W. Bush coasted to an easy victory, taking anywhere from 40 to 50 percent of the state's Hispanic vote with him. Thanks in large part to Bush's wide coattails, all 28 statewide officers in Texas are now Republican."
Perhaps he is hoping for the same thing nationwide.
