It won't, but the (real) Left hasn't done anything of particular significance in the U.S. in the past forty or so years? (I don't mean the "gay rights" and "diversity," etc. dog-whistling, modestly successful at best attempts at gun-grabbing, or Obamacare, or whatever lame manufactured and/or just plain not-actually-Left things, while the late-capitalist state and corporate apparatus continues to chug on like a runaway train.) There will surely be a resurgence, but the Trump movement itself was a resurgence, and both sides are both empowered (and simultaneously, paradoxically, by "slacktivism") paralyzed by the Internet (and to some degree partisan news and radio as well.) Either way, I expect "interesting times" (in the Chinese sense) in years to come. I am not sure how close we are to political violence.
To revolution and counterrevolution and widespread rioting and people being dragged away in the middle of the night, probably not, but I wonder. The two most extraordinary revolutionary political forces of the 20th century came from rather rag-tag origins, all you really needed, then anyway, was some intellect, some charisma, and some muscle, most of all, a "good crisis not to let go to waste" and situations in which the military and police apparatuses are splintered from the State, or ineffectual; the NSDAP, after all, started as disaffected a few reactionary theorists backed by SD beer-bar bullies of questionable morals and muscle for NSDAP from the various reactionary Friekorps of veterans; the Bolsheviks started began as disaffected petty intellectuals turned exiles, drawing their muscle from rural and urban riffraff, both aided and abetted by the experiences of the Great War and meddling that happened in their respective countries and movements by outside elements.
Now, the modern surveillance state wouldn't allow all of that (and remember, "right wing militias" were labeled as "the greatest domestic terrorist threat" by the Obama administration, that is, the same Clinton-era "black helicopter" and "militia" crowd, many of whom, just like so many left-wing movements, were coöpted by spies and agents provocateurs mostly from the FBI—the secret police of a country that "doesn't have a secret police"—and even more shadowy agencies.)
The thing is, that there really is only "one party" in power, the neoliberal-neoconservatives, Trump jumped the line a bit and on occasion refuses to tote it (although the majority of his appointees, Sessions probably being a genuine counterexample, tend to belie the latter tendency.) The almost-inevitable seeming President Pence is surely on the righter end of the Republican spectrum, but the spectrum between the two "parties" is not that great at all on their core loyalties, orientations and ideologies.
So looking for a "revolution" may have both "sides" severely disappointed, the least either of our "sides" can likely hope for is to stave off whatever in the other that we find the most noxious (which for me, and probably for many of my friends on the left, be around issues of identity; while at the same time, my hopes for a new socioeconomic order and "social justice" in the traditional sense of the word would be far more at home amongst Bernie Sanders and those considerably to the left than him than my ideas on identity, whereas soi-disant "liberal"[U.S.] politicians present an almost perfectly exacting opposite inversion.)
