SurveyUSA is out with another poll of the Governor and Senate races in Oregon; the last one seemed very outlier-ish at the time, but with subsequent polls from a variety of pollsters all pointing to a tie or slight Dudley lead, this is very much in line with everyone else. (Rasmussen, for instance, just saw the Governor's race at 47-44 for Dudley and the Senate race at 51-35 for Wyden, eerily similar.) Another thing that leads me to be afraid this is close to the mark: the frequent SurveyUSA quirk with young voters isn't present here. The 18-34 set loves Kitzhaber, giving him a 51-39 edge; Dudley's lead is built on senior citizens.
Still, much of Kitzhaber's problem is that he hasn't bothered going on the air yet, partly because he anticipates being outspent and needs to conserve his resources, partly because (as I've belabored before) that he seems to be operating with the same ill-advised sage Zen-master sense of invincibility as Jerry Brown next door. If it's not working as well for Kitz, it's because Oregon isn't quite as blue as California, with the GOP-leaning hinterlands making up a bigger percentage of the state. At any rate, he seems to be realizing he needs to get his name out there, and he's out today with his first TV spot, a positive and job-o-centric ad.
