"Having a PAC gives us more tools that we can use to fight — especially when it comes to express advocacy for or against a candidate. If our competition and the opposition, the people who are not for fiscal responsibility, if they're using all the tools at their disposal and we're leaving some of the tools on the sideline, we may not be fighting as effectively as we could be," she said.

A number of other Tea Party groups, including Tea Party Express and regional-based groups like the Independence Hall Tea Party, which operates in the Northeastern region of the U.S., have launched PACs that were active in the last cycle. Martin indicated the TPP's initial reluctance to develop a political action committee was due to the group's emphasis on grassroots organizing and a more diffuse power structure.

The decision to launch a PAC, however, could indicate that TPP plans to get more heavily involved in primary contests.

Outside groups played a large role in primaries this past cycle, and a number of Tea-Party-backed candidates, including GOP Rep. Todd Akin in Missouri and Richard Mourdock in Indiana, toppled establishment candidates in their nominating contests.

But both Akin and Mourdock failed to prevail in races that initially appeared likely wins for the GOP, and national party operatives have indicated that the establishment plans to play a larger role in primaries this year to prevent similar outcomes. TPP's PAC could be the force against the potential for increased establishment involvement in those primary contests.
