The internal conflicts that have roiled the Republican Party since its dismal showing in November appear to be deepening as conservative activists and tea party officials have begun to loudly resist an establishment effort to blame them for the GOP's 2012 troubles.

The nation's largest tea party organization is launching a new federal political action committee, Tea Party Patriots Citizens Fund, aimed at challenging GOP incumbents and other establishment candidates to adopt more conservative positions.

"If we are going to change Washington and save America, the tea party movement must hold every politician who supports higher taxes and even higher spending accountable — regardless of their political party. If that means we have to defeat some of these big-government politicians in primaries, so be it," said Jenny Beth Martin, national coordinator of Tea Party Patriots, in a statement earlier this month.
