Maybe we'll have to settle for watching the Ryan-Feingold debates in 2012:
Wisconsin Sen. Herb Kohl will announce his retirement today according to an informed Democratic source, a decision that sets up a competitive open seat contest in a state that has already drawn considerable national attention this year. [...]
Rep. Ron Kind and well as former Sen. Russ Feingold are sure to be leading candidates for Democrats. Former Rep. Tom Barrett, who ran lost to Walker last November, as well as Reps. Tammy Baldwin and Steve Kagen are also mentioned.
The Republican nomination is Paul Ryan's for the taking, as is the Democratic nomination for Russ Feingold. Corporatist "New Democrat" Ron Kind wouldn't stand a chance in a Democratic primary, it seems to me.
While Feingold lost his seat in the 2010 Republican wave, he's not really damaged goods. He only lost by 5 points, 47 percent to 52 percent. The recent state supreme court election shows that Wisconsin remains as much a battleground state as ever. And Obama could help bring out the youth vote that didn't really show up for Feingold in 2010. The 18-to-29-year-old demographic dropped from 22 percent of the electorate in 2008 to just 15 percent of the electorate in 2010.
So it seems to me that a race between Paul Ryan and Russ Feingold would be quite competitive, and as entertaining as it would be enlightening. Who wouldn't like to watch Ryan, the best conservatives have to offer, debate Feingold, the best progressives have to offer?
