From that site: Use this forum to post your ideas about how we can rebuild the party. The best ones as voted by the community may be incorporated in the plan we deliver to candidates for RNC Chairman.
All four of those ideas are on the Top Ideas list, but the two FairTax ones currently don't come close to comparing with the votes that the Ron Paul (currently rated at #1) and Libertarians (currently rated at #2) ones have. Ron Paul is a FairTax supporter, though.
Whether Republican, Libertarian, Independent, whatever, go and take a look at the site. Vote for the ideas you like or submit your own. Let your voice be heard and let's get the GOP back to the way it's supposed to be.
