I’m hopeful, but not really optimistic. Last time Republicans had it all, all we got was more spending and bigger government. Until true conservative principals are applied, nothing much will change.
The difference may be that the GOPe has been taking heavy shelling from their own right flank for several years now and the conservatives are getting stronger every election.
The leadership will complain because they are not used to being told what to do, but they will begin moving in that direction.
