In 2002, Doyle was elected with only 45 percent of the vote because of an unusually strong challenge from the Libertarian party. Although his early 2006 approval rating was a mildly unfavorable 45 percent, he led both Republican challengers, Milwaukee County Executive Scott Walker and Congressman Mark Green by six to nine points in polls; he has not been able to poll greater than fifty percent. Green got a big break when Walker dropped out of the race. And more recent polls show that Green has pulled even. Wisconsin is a swing state in the strongest sense, with George W. Bush losing the state by some 5,700 votes in 2000 and around 12,400 votes in 2004, although they hadn't voted for a Republican for president since 1984, and they hadn't had a Republican senator since 1993. An October 18 Rasmussen Reports poll has Doyle leading Green 48% to 44% and an October 31 Research 2000 poll has Doyle leading Green 50% to 44%. Democratic incumbent Jim Doyle was re-elected.
