As you can see, @dscc nabbed a few great recruits that put the chamber in play, but there are also a few key missed opportunities that sorely stick out (see the lower right area).

MT could also have become a Lean R race with Steve Bullock, and KY could have with Rocky Adkins or Matt Jones.
They got perfect candidates in CO, AZ, and ME, passable ones in NC and IA, and good enough ones in KS and AK to make these usually very-red states possible wildcards.
KY and SC won't be competitive but could be money sucks for the GOP, too.
