Effects of a Huckabee nomination

There is a post on Powerline about what would happen if Mike Huckabee gets the Republican nomination. It goes into lots of detail about what I ranted about after his Iowa win:

If Huckabee goes on to win more primaries he will have a reasonable claim to the nomination. He may, of course, lose New Hampshire, New York, California and Michigan. But let’s suppose that he manages to win enough primaries in the southern and border states to make the results in those three states irrelevant. It’s all a question of numbers. In spite of itself, the party might end up with him as its nominee, and with it, heading down the shortest road to disaster since the Goldwater debacle of 1964.

Make no mistake about it: an electoral defeat of these dimensions would represent a major watershed in the history of the Republican party. It would be faced with only two possible roads forward. One is to become the party of the religious right, a sectarian agglomeration somewhat like the small ethnic parties in inter-war Europe, perhaps capable of holding some governorships and seats in Congress but never again competitive in a presidential election. The other would be to cut itself free from the religious right and seek to appeal to the wide and growing tranche of independent voters who are socially liberal but economically conservative. In that case the Republican party would gradually resemble some of the “liberal” (that is, conservative) parties who periodically win national elections in Western Europe or Canada. These parties are friendly to market-based solutions to economic problems—that is, they are broadly libertarian.
