With a powerful Tea Party movement framing Republican policy in Washington and across the United States, Fault Lines looks into the links between the Tea Party movement, the Christian conservative movement, and Republican politics ahead of the GOP primaries.

As the race to be the Republican nominee in the 2012 Presidential election heats up, Fault lines follows the Iowa campaign trail, to understand how the far-right conservative movement is reshaping the American political debate, and to open a window onto the political landscape of the United States, its religious sensibilities, its fears, and possibly its future.
