Wouldn't it be funny if a Democrat other than Sebelius beats Tiahrt or Moran?
I hardly think such a creature exists.
It's a huge 'what if', but what if Tiahrt and Moran tear each other into shreds, to the extent that Jay Love and Harri Anne Smith did in the AL-02 Republican primary election in '08? Democrats have at least a couple options including Mark Parkinson and Dennis Moore that could actually give us a run for our money.
Dennis Moore isn't going to run, and Mark Parkinson has already taken himself out of contention for Governor, so it seems less likely that he'd run for Senate. At this point the only possible half-decent Democratic candidate is Nancy Boyda.
