That sounds like a recipe for permanent minority status. Conservatives are only about one third of the electorate according to exit polls in 2006 and 2008. Without attracting the small 'l' libertarians, variously estimated at 10 - 15 percent of the electorate, I don't see any hope. The numbers are not there. Then you still need a mix of moderates and independents to get over 50 percent just for the popular vote.
Political parties that have principlesattract voters to their ideals. If we are true to our conservative principles and provide a contrast to the left wing drivel of the other side we will attract voters. That is what Reagan did. By and large most people have conservative values, though when asked they don’t self identify that way. An all inclusive party ends up trying to placate everyone and stands for nothing. Give the people in charge of the democrattic party their due. They know what they stand for. Obama did not move to the center to win the election, McCain did and what it got him was nothing. Conservatives could try to take over the GOP, but that would mean a long drawn out struggle with the Rockefeller country clubbing RINOS and does not guarantee we’ll win. It’s time to let the GOP float on it’s own and let it sink to the irrelevance it justly deserves. It pains me to have to say this. But after many years as a republican I have come to the conclusion that drifting it to the right is a hopeless cause.
