Defund the GOP?

Recently, Glenn Beck called for the defunding of the GOP, and it was received with great enthusiasm. The idea came in response to a story about the Speaker of the House, Representative John Boehner. The corruption of the GOP seems to know no bounds. But is calling for the defunding of the GOP really the right option? Is this the best strategy with which Conservatives can change their country for the better? I am not convinced. Perhaps the GOP is so corrupt that our only option is to destroy it, I am not saying that is not a possibility. However, I am asking the question: Is this the best time and place to begin calling for the defunding of Conservatives. Please do not misread this question as rhetorical. This is an honest question. Should we as Conservatives simply take to politics in a "purist" fashion? Or should there be some sort of alternate strategy? Will this increasingly powerful grass-roots party hurt or help itself with these strategies? These are questions that need to be considered.
