Reid did not directly address the issue of religion, but criticized Romney, the front-runner, for changing his position on issues such as gay marriage, saying “he doesn’t know who he is.”

“Here’s a man who doesn’t know who he is. He was for gay marriage when he was governor. Now he’s against it. He was for abortion when he was governor. Now he’s against it,” he said.

The Nevada senator also said that Democrats modeled their healthcare law after the measure Romney signed in Massachusetts.

“Now he’s trying to run from that. If someone doesn’t know who they are, they shouldn’t be president of the United States,” he added.
