Did God Tell Herman Cain to Run for President?

I don't usually talk about politics here but I could not pass this up.

It seems presidential hopeful Herman Cain is a modern Moses:

Herman Cain returned to his home state for a brief campaign stop Saturday, telling a cheering group of young Republicans in Atlanta that God told him to run for president and that he was "in it to win it."

"I prayed and prayed and prayed. I am a man of faith," Cain told the Young Republican National Federation at the Westin Peachtree Plaza. "I had to do a lot of praying for this one, more praying than I have ever done before in my life. And when I finally realized that it was God saying that this is what I needed to do, I was like Moses: 'You have got the wrong man, Lord. Are you sure?' ... Once I made the decision, I did not look back."

So what should I do if God told me not to vote for any candidate who claims to have been told by God to run for president?
