McKenna has been saying and doing a lot of crazy teabaggy stuff lately that will be fun to use in TV ads against him. His moderate facade is going to go away pretty quickly once this gets going.
Is Gregoire seriously considering running again? If the nominee is Inslee I think, he has a shot at this seat, but it wont be more than a toss up throughout the campaign (see Washington 2010 Senate Election). I do think, however, Republican's have a top tier candidate in McKenna and that with a good campaign he can win.
Nah, she's just hinting that she might so folks can't label her a lame duck in Olympia. There's no way she'll run again.
