It is unfair to accuse social conservatives of waging a culture war.

[Cashew]

-Not to nominate a criminal
-Not to insult millions of Americans
-Not to nominate someone with baggage and a high unfavorability rating
-Not to pick a nominee who will suppress the Progressive wing of the party

That is just a few of them.

Basically this and some other things mentioned in this thread. I'd also add that their obsession with social issues is really hurting them in the rural and suburban areas. While I don't think they will move to the right when it comes to social issues, they would do best if they focused on economic issues.

What obsession? I'm sorry but just because Trump won doesn't mean reality gets rewritten. In all these major social issues from trans-bathrooms, gays being denied services, etc... have all been made issues by cons not libs

I am not going to make any generalizations, but the textbook defenition of your average conservative is to preserve the status quo, while the average liberal wants to change it.

Therefore I conclude that despite noble intentions, liberals are in fact the real agressors when it comes to waging a culture war.
