VIDEO: The Week That Was: Romney win changes perception

With Mitt Romney looking to be the likely nominee, Rick Santorum looks to Texas in hopes to help his chances.

 

With Mitt Romney's win in Wisconsin, perception shifted in this campaign -- from Romney as struggling front runner to likely nominee.

The question then became if and when Rick Santroum would drop out.

But Santorum, who met with conservatives at his home in Virginia Thursday, showed no signs of ending his campaign.

Instead, in that meeting, Santorum backers were trying to chart a way forward. The strategy they came up with hinges on: (1) getting Newt Gingrich out of the race, and (2) getting Texas to change its rules on how it allocates delegates from proportional to winner take all.

Well, if that that sounds like a lot, that's because it is. And it's not likely to happen.

Gingrich said there's no chance he's dropping out and telling his delegates to go to Santorum, and Texas would need a waiver from the Republican National Committee to change its rules. But RNC sources tell NBC News there is little change of that happening.
