So far the winner of the GOP primary in my state, South Carolina, has ALWAYS gone on to win the Republican nomination. Unfortunately, last time around, the winner was McCain.
Both states are attention whores and atypical of the average voter. New Hampshire is famous for economic conservatives who p*ss on social conservatives. Iowa is famous for social conservatives who love pork and economic populism a/k/a redistribution. Both are repugnant to real conservatives who should believe fervently in both economic and social conservatism, sort of like they do in South Carolina.
