Ed Gillespie, a senior adviser to Mitt Romney, suggests that gay marriage will be part of the debate.
"His [Romney's] position is clear. He believes marriage should be between a man and a woman.
That was President Obama's decision up until obviously 24 hours ago, and now this will be another bright line difference in this campaign."
A bit later, MSNBC host, Chuck Todd, asked if Romney would campaign on the issue.
Gillespie answered "Sure, I think it's an important issue for people."
