Greg Sargent calls it the “MAGA doom loop” : For almost three years now, Republicans have defended or embraced Donald Trump’s authoritarianism — from lies about his 2020 loss to inciting an insurrection — which backfired as Americans proved unexpectedly eager to vote in defense of democracy in the 2022 elections as well as in contests this year. But Republicans aren’t giving up — they’re going even further. To an unappreciated degree, they have responded to these electoral losses with even more flagrantly anti-democratic maneuvers all around the country. The pattern is becoming clear: Even as voters are mobilizing to protect democracy at the ballot box, Republicans are redoubling their commitment to the former president’s anti-majoritarian mode of politics. And this, in turn, is motivating voters even more. Call it the “MAGA doom loop.” It’s playing out in state after state. Let’s start with Michigan, where Trump’s decisive loss in 2020 led MAGA loyalists to reshape the state Republican Party around devotion to the “big lie.” Then Democrats resoundingly captured full control of the state’s government in the 2022 midterms, in which election-deniers across the country lost races up and down the ticket. Now, the Michigan GOP is in shambles. Just this month, the chairman again called for scrutiny of supposed 2020 fraud, prompting infighting over debunked conspiracy theories. And as the New York Times reports, the party’s descent into MAGA mania is alienating donors, draining volunteer enthusiasm and driving away swing voters. All of that will further dim Trump’s 2024 chances in this crucial battleground state.…
