Lets see Bustamante wants to increase spending and raise taxes and Arnold wants to do the opposite. Bustamante wants to regulate the hell out of business, Arnold wants to do the opposite. Bustamante wants to give California back to Mexico while Arnold supports Prop 187 and opposes giving illegals California drivers licenses. Only a blind McClintock or Bustamante supporter could miss those major differences.
McClintock, the principled conservative can beat Bustamante if it's one on one. But first the "I like McClintock but..." crowd have to get behind him.
