In 1988 Bob Dole, after winning the Iowa caucus was defeated by Bush in New Hampshire. The question is what if Dole won the primary? Would he have got the GOP nomination and won the election?
Dole probably has a better chance in 1988 than he did in 1996... of course the Republicans could have beat Dukakis with almost anyone. I say almost because Dukakis would have blown away Pat Robertson.
