more aggressive, hard-hitting campaign against newt gingrich to stop him in his tracks? and how will his decision not to attend donald trump's event play with republican voters? well, chris cillizza is managing editor of postpolitics.com and an msnbc contributor, and maggie haberman is a senior political writer for politico. i want to start with maggie. maggie, it's very interesting to try to find the power in the republican party. you know, in the previous cycles, i'd refer to it like a lot of us, sarcastically, as the white boy's club, a group of governors, perhaps, who would meet somewhere, at some club somewhere, and sort of give the official okay to whoever the candidate was, particularly george w. or someone like that, or his father. now the power vortex seems to be coming either from radio in the voice of rush limbaugh or this manhattan project of donald trump. i mean, where is the republican power base today that seems to be, well, influencing the selection process?
