And if he does win the primaries, will he have established a suitable coalition for you?
You seriously misunderstand the nature of the coalition that has been voting or nearly voting Republicans into office over the last 2 decades. Reagan Democrats and Independents don't vote in Republican primaries. While Giuliani may fool enough gullible Republicans into voting for him despite his oppositional position on most Republican issues, but that does not mean that he can gain/retain the support of the larger loose coalition of voters required to elect a Republican.
