Sahil Kapur has a good piece up at TNR about the Tea Party's plans to go after Mitt Romney because he's not the "rock-solid fiscal conservative" they want. According to Kapur, FreedomWorks, the Dick Armey-led Tea Party organization, is threatening to "uneash part of its $25 million treasure trove in an attempt to sink his candidacy." Meanwhile, Joe Miller, the Tea Party candidate who took on Lisa Murkowski in Alaska and lost last November, has his own political action committee dedicated to going after Mitt Romney where it matters most: New Hampshire.
