There was a big shift in Congress in 1994, though... and Clinton didn't really govern as a hardcore liberal. He was more interested in soaking up admiration and chasing tail than in pushing a leftist agenda.
So we shouldn't work to take back Congress so we can set up the perfect situation for the next "real conservative leader" to take us to the promised land? I don't think so. We should just accept the fact that we couldn't agree on a consensus Conservative and got McCain for our efforts AND we should work to elect conservatives to Congress. This would drive McCain to the right. If McCain does succeed in his strategy to be elected by moderates, independents and democrats... he will need a more conservative Congress than we have now to drive him to the right (as Clinton did in 94). We should have been working on this all along.
