Get free media time. Get involved in your local Tea Party, then call the media and say you're available for interviews.
I was interviewed by the local PBS affiliate regarding the upcoming Tea Party. So was the county CFL coordinator.
As April 15 approaches I expect to do more interviews with local media. First you get one interview. Then, you call the other media up and say "I was interviewed by such-and-so media outlet, and I want to let you know I'm available for interview with you as well."
