The larger point, though, is that with seven weeks left to go, McMahon has made this a race and Democrats’ best efforts to stall her candidacy have not worked. This, of course, could certainly change as they start airing negative ads against her, but for now McMahon is in the hunt, handing Democrats a race in an expensive blue state that they weren’t expecting.
Seems like anything is possible in 2010.
