Two polls out this morning confirm the dire current environment for Democrats. PPIC, a respected firm in California, finds Republican Senate candidate Tom Campbell,who has had trouble in state GOP primaries because he is not perceived as a true conservative populist, within four points of incumbent Barbara Boxer. (In the primary, Campbell leads Carly Fiorina by 11 points and Chuck DeVore by 19 points.)  In the gubernatorial race, there are plenty of undecideds: Jerry Brown (D) is at 41%, but leads Meg Whitman (R) by five points. In Wisconsin, an IVR poll by Rasmussen shows Russ Feingold to be in trouble, but I don't know whether any Republican seriously believes that (a) Tommy Thompson will challenge the Democrat and (b) whether Feingold is really that vulnerable at the moment. (Update: I was thinking of someone else when I called Campbell a populist earlier. He's not.)
