"...If your "majority" is provided by liberals (oops, "centrists").."
Historically, and in strictest political terms, Republicans ARE Liberals. Look it up, you might learn something about Classical Liberalism, and if you do, please tell your friends.
What we refer to as "liberals" are nothing of the sort. Unless, of course, you consider government-supplied-and-controlled-everything-intruding-into-every-nook-and-cranny-of-your-life to somehow be a liberal ideal. If anything, they are certainly not liberal (if we use the word correctly), and what I think you mean to say (if you'll allow me) is "libertine", with regards to their social views.
Oh please, spare me the patronizing civics lesson. I'm way ahead of ya. Let me know when you catch up and want to have a conversation.
