I don’t know what will happen in the January 5 Georgia runoffs which will determine which party will control the U.S. Senate, but I do know that Mitt Romney really ought to caucus with the Democrats irrespective of the results there. I don’t say this because I have much respect for Romney. He ran the most dishonest presidential campaign in history prior to Donald Trump. I say it because he has no future in the Republican Party and on the most critical issues facing the country, he’s clearly on the side of the Democrats.

That’s clear from Romney’s latest statement on “the egregious ploy” by Ted Cruz and several other of his Senate colleagues to challenge the results of the 2020 presidential election.

Romney sees the “ill-conceived endeavor” as dangerous and completely indefensible, and asks, “Has ambition so eclipsed principle?”

That’s a rhetorical question. Romney may be appalled, but he knows that there’s not much principle left in his party, and none with the party’s base. He can see that his colleagues are responding to pressure from Republican voters and that all the rewards will go to those who “dangerously threaten our Democratic Republic.”

There’s no chance that Romney will ever again be the party’s presidential nominee, and there’s a good chance he’d lose a competitive primary even though Trumpism is weaker in Utah than other bright red states. If his chances of reelection are poor regardless of which party he represents, he might as well serve with the party that is on the side of the Constitution.

As for whether the Democrats should welcome Romney, that’s a tougher call. If it means they get control of the Senate, it’s a no-brainer, but that would only happen in the case of split-decision in Georgia. Otherwise, Romney would add a little bit here and there, but also take up valuable slots on committees where his input and vote would not be consistently aligned with the party’s agenda. Romney would often be more valuable as a Republican offering a bipartisan sheen to a few issues than as an actual tie-breaker.

Plus, every time a sane Republican defects to the Democrats, it makes the GOP just a little more radical.
