The RINOs are not going to give up power. Maybe the answer is for conservatives to win over black votes in an honest way. Talk about empowering neighborhoods with less federal regulations and setting up businesses and US jobs for US citizens. A positive message of things neither party is doing to empower and upgrade black and other disadvantaged US citizens could do it.
I'd wager that a campaign to send home the hordes from central america before schools open would be a huge winner, bringing over a lot of dem voters.
