Daily Show host Jon Stewart on Monday night analyzed the less-than-enthusiastic endorsements of Republican presidential candidate Mitt Romney.

"Look, Romney is going to be the nominee. Everybody's decided. They're all getting behind him. What they haven't really decided is why," he said.

Many Republicans have offered mild endorsements of the former Massachusetts governor. But some Republican endorsements of Romney have been outright critical.

"I am endorsing him... now Mitt is not a perfect candidate," former New York Gov. George Pataki said in a clip played by Stewart. Pataki said Romney had a "number of problems," because it was hard for blue collar families or economic conservatives to relate to him.

"These are his supporters," Stewart noted. "For God's sake, this is presidential politics. Fake it better."
