This really is the most important midterm election … ever!

Politicians say it all the time. It doesn’t matter their partisan affiliation — Republican or Democrat — they sing it off the same song sheet.

“This is the most important election in our history!”

That’s what they say. They might mean it. Or they might be saying just to fire up their respective supporters.

Guess what. I think this election, the 2018 midterm, actually is the most important midterm election in U.S. history.

What’s at stake? Plenty, man!

Republicans control both chambers of Congress and the White House. The executive branch, the White House gang, is being led by a man, Donald J. Trump, who doesn’t know what he’s doing. He entered the presidency without a lick of public service experience, let alone any interest. He is a dangerous fellow who doesn’t grasp the limits of his power, or how the government is designed to function.

The House of Representatives presents the Democrats with their greatest opportunity to seize the gavel from their GOP colleagues. They need to do precisely that if for no other reason on Earth to act as a check on the runaway agenda being pushed by Donald Trump and endorsed by a GOP congressional majority that is scared spitless of the president.

I am among those who believe the Senate is likely to remain in Republican hands when the ballots are counted next Tuesday. Indeed, it appears to be entirely possible that the Senate’s GOP majority might actually increase by a seat or two; Republicans occupy 51 seats at this moment, with Democrats (and two independents who favor the Dems) occupying 49 seats.

The House, however, must flip. It must act as a check on Trump and on the GOP members of Congress who give this seriously flawed president a pass on so many issues. They excuse his hideous behavior; they refuse to call him out vigorously when he refuses to condemn haters — such as the KKK and neo-Nazis; they roll over when he pushes for repeal of the Affordable Care Act or enact tax cuts for the wealthiest Americans; they pledge to cut money for Medicare and Medicaid to help curb the spiraling annual federal budget deficit.

Divided government has worked in the past. Barack Obama had to work with a Congress led by the other party. So did George W. Bush. Same for Bill Clinton. Ditto for George H.W. Bush and Ronald Reagan.

It lends a greater air of a need for compromise.

If the Democrats fall short on Tuesday, clearing the path for Trump and the GOP to run roughshod over the rest of us, well … we’re going to have hell to pay.

Yes, this is the most important midterm election in U.S. history.
