Feingold No Longer the Golden Boy?

I do not agree with Senator Feingold's political views but I do have give him his props for sitting through his listening sessions. The Senator seems to be running into a fair amount of opposition from his constituents for voting yes to some very unpopular legislation. Here are video clips from Pewaukee, WCTC and Oshkosh.
Could it be true that there is a chink in Feingold's armor? Could this be the year the radical lefty is ousted from the seat that his butt has indented for the last 17 years? Be still my heart.
