Democrat governorships have dwindled in number. Kentucky now has a Republican governor.
The Democrats' choice last night may also signal a lack of faith in Democrats on Capitol Hill. Or at least some second guessing of the obstructionist games Pelosi and Schumer are playing.
If Kentucky's Steve Beshear wasn't already 72, I'd guess Dems were setting him up for a potential presidential run.
But no, most likely, they were just recycling old stock, trying to look mainstream American as they take their party deeper into progressive territory.
