From where we're sitting in the UK, the Democrats are, more or less, fairly hard right, and there has never in the history of your politics ever been a Republican that could be considered "moderate." It's all relative, of course. I suppose that a Republican who isn't actually a xenophobic, warmongering Christian evangelist might be seen, at least on the Republican spectrum, as "moderate." But I can't think of many. Your Republicans are like our Tories: self-interested, big-business right-wing capitalists who believe in "freedom" for their own kind but to hell with the rest.
