Could it be that Democrats and GOP both are doomed?

For all the obvious reasons, the Republican Party gets most of the attention these days. For starters, it controls the White House, the Senate and the House, and the party in power always warrants more scrutiny, even when it’s operating smoothly.

Of course, that’s not happening.

The GOP is running as smoothly as a dry Slip ‘N Slide made from sandpaper. This stems from a host of ideological, political and structural problems that are only compounded by the fact that the president grabs the public’s attention like a spider monkey running around with a lit stick of dynamite.

The Democratic Party, meanwhile, has gotten drunk on the spectacle. And as with many a drunk, it’s grown oblivious to its own decrepitude.

Donna Brazile, the longtime Democratic functionary, was made interim chair of the party shortly before the 2016 election in the wake of revelations that the previous chair, Debbie Wasserman Schultz, seemed to be playing favorites in the primaries, tilting the scales toward Hillary Clinton and against Bernie Sanders. In an excerpt from her forthcoming book, “Hacks,” Brazile reports that Wasserman Schultz wasn’t simply partial towards Clinton. She was in fact Clinton’s vassal.

Team Clinton mocked Sanders as a dotard for claiming that the Democratic primary system was rigged against him. As it happens, his paranoia didn’t go far enough.

Today, the Democratic Party’s sole unifying principle is opposition to Donald Trump. Given Trump’s standing in the polls, that may be good enough for the 2018 midterms. But when it comes to ideas about governing, all of the passion is reserved for two things.

First, there is Sanders’ idea of “socialism,” which is really an unworkable stew of banalities and nostrums stemming from a nostalgic idea of a “Scandinavian model” that no longer exists (if it ever did). It’s as if Fabian socialists created an Epcot Center exhibit of Sweden in the 1950s, and irascible tour guide Bernie rides by in a trolley, shouting: “This could be us!”

The second source of passion is the angry, sanctimony-besotted identity politics popular on college campuses and a handful of left-wing websites. The DNC’s data services manager recently sent out an email soliciting applications for new hires in the IT department. She cautioned that she wasn’t looking for any “cisgender straight white males.”

If you want to know how Trump was elected, ask yourself how a laid-off, cisgender, straight, white, male coal miner who went back to community college to learn computers might react to that.

Again, you wouldn’t be crazy for thinking the GOP is like a runaway fire at a soiled diaper reclamation center.

But the important point is that dysfunction isn’t zero-sum. Right now, the best argument Republicans have is “we’re not Democrats,” and the best argument Democrats have is “we’re not Republicans.” Like two punchdrunk pugilists leaning on each other in the 12th round, if one falls, the other may well fall too.

Everywhere else in America today, disrupters — Uber, Amazon, etc. — are dismantling established institutions. Perhaps both political parties are the next institutions to crumble under creative destruction. Or maybe not. But if it happens, no one can say they didn’t have it coming.
