(...) The question that has dominated the GOP contest is, "Should we nominate someone as liberal as Rudy on social issues?" The answer among the stalwarts is obviously no. As long as the social conservatives are divided among four candidates, Rudy has a shot. But when they rally behind one man (probably Huckabee) conservatives outnumber moderates in Republican primaries, particularly if the independents are drawn into the Democratic primary by Hillary's new vulnerability.
But by losing, Rudy shifts the focus. Republicans will ask, "Is America ready to elect a Mormon?" (unfortunately not) and, "Are we ready to go with Romney or Huckabee who have no experience in foreign or military affairs?" Once again, Rudy will profit from the shift in focus his defeat in the early contests will trigger.

(...) Remember how Gary Hart beat Mondale in New Hampshire in 1984 and Mondale came back to win? And how Paul Tsongas beat Clinton there in 1992 and Clinton eventually won? And how McCain defeated Bush in New Hampshire in 2000 but how Bush came back to win? Different year. New candidates. Same deal.
