This is a populist message but there is no inconsistency between this populist message and true conservatism. Reform of a government policy is not "populist" in the pejorative sense if it restores balance. It is not a leftist position to undo the harm done by government.
No thanks! We've been doing that for years, and all it has done is push the Republican party further to the left. Are you left wondering why we have such liberal leadership in the GOP? It's because we keep trying to turn democrats into republicans! We may accomplish this on some levels, but there are factions, such as the socially liberal, who maintain those socially liberal views despite the fact that they vote Republican. So, they are going to vote for the Republican who best supports social liberal issues, such as gay marriage. Instead, it's time to shore up the base and solidify Conservative values across the board.
