Diehard Anti-Iraq War crusader Democrat Sen. Russ Feingold, has fallen substantially behind a candidate who hasn't even announced.

In the latest poll just released by the Wisconsin Policy Research Inst. affiliated with the Univ. of Wisconson-Madison, Tommy Thompson leads Feingold 51% to 39%. (Source: Milwaukee Journal)

Feingold has already gone on the attack, accusing the former Governor of being a tool of Washington insiders. In a recent email, according to FreedomEden, he said the following:

"I’ve spent years and years taking on the special interests. And Tommy Thompson spent years taking them on as clients."

Feingold is best known for his fierce opposition to President Bush and the War in Iraq. He was one of only a handful of Senators to vote against the resolution to go into Iraq in 2002. Then later on he made the unusual move of threatening to cut off funding for the Troops while still in the battlefield. Finally, he called other Democrats who still supported the Military "timid."

Note - Tommy Thompson is the brother of longtime Libertarian Party member and Mayor of Tomah Ed Thompson, who is currently a Republican candidate for State Senate.
