MADISON, Wis. (AP) -- Attack ads, allegations of wrongdoing, fights over campaign donations and every so often -- an argument on the issues. The governor's race in Wisconsin has turned out to be just as pricey and nasty as many predicted.

Jim Doyle ended 16 years of Republican control of the governor's office with his victory in 2002. He's attempting to become the first Democrat re-elected governor in 32 years.

His challenger, Republican Congressman Mark Green, previously served in the state Assembly.

The campaign has been a bare-knuckles brawl for months.

The Wisconsin Democracy Campaign estimates the final price tag for the race will top out at $30 million -- the priciest governor's race in Wisconsin history.

Millions of dollars were spent on advertising, with more than a third coming from independent groups attacking one candidate or the other.

Democracy Campaign Mike McCabe says it's a painful campaign to watch. He says it's degenerated into two candidates trying to prove the other is a bigger crook.

Doyle's popularity rankings have consistently been around 50 percent or less, while Green came to the race as a member of an unpopular Congress. Since both were vulnerable to attack, that's the road the campaigns took.
