Coakley was just lame and really sucked. There was nothing controversial about her.
I don't think Moore winning would hurt the GOP in 2018 because people will have already moved on to other things. Small attention span in this country. I don't think he'll win anyway so it doesn't really matter.
This is exactly my point.
Controversies just aren't an object anymore because of this, unless you get a very targeted, endless character assassination campaign [as seen last year with the "buh her emails"] OR a candidate really manages to shoot his/herself in the foot that many times [Trump, and possibly Moore now], tribalism overrides it all.
