1. With news that the number of uninsured people in the United States is at its lowest since 2008, and news that 7.1 million people enrolled for health care in federal and state exchanges, things are looking up for Obamacare's public image. Does that mean Republicans need to start recalibrating their 2014 election strategy? Former RNC Chairman Michael Steel and Eric Boehlert, Senior Fellow at Media Matters, join us.
2. Former Port Authority official David Wildstein, a key figure in the "Bridgegate" scandal that has engulfed New Jersey Republican Gov. Chris Christie's administration, is reportedly cooperating with federal prosecutors. We'll discuss with Bob Ingle, Senior Political Columnist for Gannett New Jersey Newspapers and author of "Chris Christie: The Inside Story of His Rise to Power."
3.

4. Plus, a look at the GOP's possible 2016 front-runners making waves: Kentucky Sen. Rand Paul charged former Vice President Dick Cheney with supporting the Iraq War so that Halliburton, the military contractor where he was previously CEO, would profit. And former Florida Gov.

We'll talk with Michelle Goldberg, Senior Contributing Writer at The Nation, MSNBC contributor Victoria Defrancesco Soto, and Robert Costa, National Political Reporter for The Washington Post.
