I’m skeptical about Republican Tim Michels beating Democratic senator Russ Feingold in the Wisconsin Senate race, but a friend at the NRSC just sent me tracking numbers that show Feingold’s lead slipping from 13 points to 5 points in four days:
10/26 — Feingold 52 percent, Michels 39 percent
10/27 — 51-41
10/28 — 49-41
10/29 — 48-43
Some Republicans have said all along that Wisconsin is their dark-horse race.
