If you want a sense of how Obama’s cynical, money-driven gay marriage evolution ploy will play in key states Obama won in 2008, look not only at North Carolina’s vote Tuesday, but also at how fast Joe Donnelly is running away from Obama on the issue:

U.S. Senate candidate Joe Donnelly reiterated his position Thursday that marriage should be between a man and a woman, saying he didn’t feel pressure to change his views a day after fellow Democrat President Barack Obama said he supported same-sex marriage.

His campaign released this statement:

Joe believes marriage is between a man and a woman. He believes it is an issue that each state should decide, and he is opposed to an amendment to the U.S. Constitution.
