Fox News Sunday went after Tea Party U.S. Senator and potential 2016 Presidential candidate Marco Rubio (R. FL) for pulling his support for the U.S. Senate's immigration reform bill due to political motivations. Rubio tried to deny it Wallace wasn't having it:

Wallace displayed polls showing Rubio's favorability taking a hit since supporting the bill.

"Is that why you have now switched and said we have to do this in stages with enforcement first and any dealing with legality or citizenship for the immigrants way down the line and afterward?" Wallace asked.

Rubio said his stance on immigration reform has nothing to do with politics.

"When I got involved in the issue, I knew how difficult it was politically, but I ran for office to make a difference," he responded. "I didn’t get elected to maintain good poll numbers nationally."

Wallace then cut in to ask, "If it’s not political, why have you flipped?"

"That’s not accurate, Chris," Rubio insisted.

The senator said he and Wallace were "talking about two separate things."

At this point, Rubio would be lucky to even be considered a potential V.P. pick for 2016 but even that looks unlikely. It's not like someone like former Governor Jeb Bush (R. FL) would need him to win Florida or Ohio. Anything can happen between now and the time the GOP primary begins but don't be surprised if Rubio's flip flopping on immigration reform writes his political obituary.
