The only people unironically entertaining the possibility of a "1912 redux" in the event that Trump were to run as a third-party/independent candidate are hardcore Democratic partisans/hacks who have shockingly little understanding of how poorly an emasculated, whiny loser like Trump would perform among Republican/-leaning voters in a competitive general election between Biden and an actual Republican challenger, esp. a competent one like DeSantis.
Stop creating these ridiculous caricatures of Republican primary voters and get some fresh air.
It won't be a 1912 redux in the sense that Trump does better than the Republican nominee but if you can't see that more than enough Republican voters will vote for Trump and throw the election if he's on the ballot then it is you who believes in a false reality of who comprises the Republican electorate. And with all due respect, you predicted a Bolduc victory in New Hampshire. I'm not trying to be mean (I like you, after all) but you shouldn't immediately jump back to the assumption that your understanding of the American electorate is superior to other people on this website.
As someone who very much does not like him and has long laughed at the Republican obsession with New Hampshire in particular ("But they're white! They like guns and don't like taxes! They HAVE to vote for us!" yet they mock Democrats who think "But Florida is diverse and Latino and urban! They HAVE to vote for us!"), I am glad to see he's back to his trademark unearned smugness. I knew he couldn't hide his true self for long, no matter how wrong he was or how much he embarrassed himself, to the point any person with even the slightest sense of shame would never make a prediction again. Because after all, he did the same after 2019. Believe people when they tell you who they are.
