As a Democrat, I do not think the party has any future, and this is how whatever future we do have left will play out:
The Democrats romantic illusion of a supposed "Resistance" is going to quickly become a sad reality -- but since it was more of a loose and decentralized "coalition", it will be hijacked by the well organized factions on the Extreme Left who will view it as a mandate to adopt an ill-conceived Socialist Platform.
From there, Northern/Coastal Elitists -- who are still out of touch with the realities of the Blue-Collar core of the party itself -- will drive away the remaining Moderate, Rust Belt, and Reagan Democrats still left in the party. Identity politics and issues such as removing Confederate Statues ARE NOT THE MOST IMPORTANT THING in the minds of people who cannot find a job, let alone barely afford to put food on the table.
Vetting potential Democratic Presidential Candidates for 2020 will be priority number one here on out, while going ALL IN on the idea the Trump being impeached is a foregone conclusion.
Economic plans to revitalize the Rust Belt are based on the failures of Soviet Collectivization -- what is extremely more worrisome is this obsession of glorifying Communism and washing away the stains of a man just as evil as Hitler -- Josef Stalin.
In a few months, Trump's Infrastructure bill will pass with bi-partisan support. David Petraeus - a very fine man and the best American General in decades - is poised to join the administration and right the ship (possibly along with Newt Gingrich, which pretty much implies the GOP is going to get its act together and deal with an outlandish Trump by reducing his role as President by 99% and using the Dick Cheney/W. model).
Finally and most importantly...hubris. Simply put, who needs the First Amendment when someone you disagree with should be physically removed/shut up...yeah, 50% of Millennials will go that far.
Who the hell needs the Constitution anyway?
Trump won in 2016, what makes anyone sure he cannot do the same in 2020? Four more years of Trump on top of the three we have left is the diagnosis --- unless, ironically, we start listening to people like Charles Barkley, and Democrats move BACK TO THE CENTER.
