The Left, far better than the NeverTrump Right, grasped that Trump is succeeding, and that it has little traction in demanding economic, energy, immigration, trade, and regulatory alternatives.
Ah, mere facts and logic again. At this point the question is really whether the Democrats will continue to say and do stuff that is so stupid, time wasting, obviously based on hate, and ridiculously extreme that they will push most Independents and even some Democrats to vote for Trump in November, and leave their own Party shattered for years to come. We can hope. --Del
