Joe Biden is thrice-blessed. Not only did he win the Democratic nomination and then the presidential election, but as a result of the events of Jan. 6, he takes office when the Republican opposition is in utter disarray and likely to stay that way for a long time. None of that was foreordained, or even very likely.

“Just days ago the media and the pundits had declared this candidacy dead,” Biden marveled almost exactly a year ago after winning the South Carolina primary election by a landslide. It had been dead, too, until African-American voters in South Carolina gave him their overwhelming support.

It was the first primary he had won, and it put him back in the race. Two days later, Biden won 10 out of 14 states on Super Tuesday and practically wrapped the nomination up. But if South Carolina had scheduled its primary even a few days later, he would have gone into Super Tuesday as a “loser,” and probably been written off.

So he got lucky once, but it was a bad year for a Democrat to be running for the presidency. Donald Trump was mocked and loathed by the rest of the world and by almost exactly half the U.S. population, but Trump’s “base” didn’t care and the U.S. economy was in excellent shape.

The U.S. media were doing their best to make the presidential race look exciting, because that’s what they were going to have to talk and write about through most of 2020. But the fact is that incumbent U.S. presidents running for reelection when the economy is good almost always win.

Biden’s second stroke of luck came just 10 days before he won the South Carolina primary, when the first case of COVID-19 showed up in the United States. By March it was running wild, but Trump, aware that his reelection depended on a booming economy, avoiding taking any public health measures that would slow it down.

Trump’s refusal to back anti-COVID measures like stay-at-home orders was driven more by electoral concerns than ideology: stall the economy and he could lose the election. But, of course, mass death also will stall the economy in the end, so he couldn’t win. He ended up with a crashed economy, 400,000 COVID-19 deaths and a lost election, too.

And then, incredibly, he gave Biden another gift: the assault on the Capitol by his followers two weeks ago.

Biden was facing a grim time in office, with at least 70 percent of Republican voters and a majority of Republicans in the House of Representatives seduced by Trump’s Big Lie that he really won the election by a landslide, and that the Democrats had somehow “stolen” it. It was Adolf Hitler, not Joseph Goebbels, who gave the technique that name, but it still works.

“In the big lie there is always a certain force of credibility,” Hitler wrote in “Mein Kampf” (“My Struggle”), “because … in the primitive simplicity of their minds [the great masses] more readily fall victims to the big lie than the small lie, since they themselves often tell small lies in little matters but would be ashamed to resort to large-scale falsehoods.”

“It would never come into their heads to fabricate colossal untruths, and they would not believe that others could have the impudence to distort the truth so infamously. Even though the facts which prove this to be so may be brought clearly to their minds, they will still doubt and waver and will continue to think that there may be some other explanation.”

That is what Biden faced only two weeks ago: a nightmare time in office with the “Big Lie” rampant and Trump its proud purveyor. And then suddenly Trump, in his manic determination to hold onto power, sent his mob off to try a foredoomed coup in the “Temple of Democracy,” as American commentators pompously call it. End of game.

Trump is discredited even with a modest but significant proportion of his own base, and a growing number of Republican office-holders are in rebellion against the party’s subservience to the Tangerine Tyrant. Biden’s years in office will be enlivened by a vicious Republican civil war, quite likely ending in a permanent split on the American right.

Which will give Lucky Joe time to do useful stuff.
