If you are a Freeper, have no skeletons in the closet, are a fairly good speaker or can become good at it (practice/repetition makes perfect), have an inner core of finance types to help you $$$-wise, are in a purple, marginal congressional district which can go either way, and HAVE ALWAYS THOUGHT OF DOING THIS, now is the time to consider setting up a committee and going for it.
I can envision at least 10 to 20 Free Republic members standing in Congressional races next year.
