Seems to me the bigger issue is changing hearts and minds through areas outside of politics. If your voter’s a brainwashed liberal based on all the media and education they’ve consumed their entire lives, one candidate isn’t going to be able to mind-wipe them in one election cycle. We had some good candidates like Dave Brat who lost this round.
I attribute that more to the typical mid-term, and how the party out of office has more motivation than our side.
I actually think this result is better for our side in 2020, because the shoe should be on the other foot.
