VIDEO: The Week Ahead: The general-election pivot


With Mitt Romney's big wins last week and the political world declaring the GOP race over, all eyes have shifted to Rick Santorum.

Santorum, a devout Catholic, is taking a few days off for the Easter holiday. His campaign, though, says he is not rethinking his plans, and he will fight to win Pennsylvania, which holds its primary April 24th. But we'll see if that changes. Polls in the Keystone State are tightening between him and Romney, and Santorum can't afford to lose his home state.

Meanwhile, Mitt Romney and President Obama are now targeting each other. Expect more of that in the Week Ahead.

On Sunday... David Gregory's guests on Meet the Press are Governor John Kasich, a Republican from Ohio, and Senator Dick Durbin, a Democrat from Illinois. They'll be talking about the general election.

On Monday... Santorum campaigns in Pennsylvania. He will STAY in the state all week trying to maintain his lead.

On Wednesday... First Lady Michelle Obama will appear on The Colbert Report. It will be her first time on the show since April 2008. Longtime Indiana Senator Richard Lugar, who is in a fight for his political life, faces off in a Republican primary debate with state Treasurer Richard Mourdock.

On Thursday... In New Hampshire, it will be the fourth in a series of swing-state addresses for Vice President Joe Biden.
