That's an attractive pair for sure. And for sure, there's no shortage of very attractive centrist candidates whom I'd love to see in office.
But the reason I think that the next US President will be a far right leaning Republican isn't that Biden per se is at fault - rather, it's that the right wants a far right candidate.
And the undecideds, it seems to me, couldn't give a flip about abortion or guns or the fact that Trump is guilty of seditious conspiracy - they're all about the bottom line - the economy.
Trump is an abhorrent figure - but that's old news. If you were undecided about Trump in 2016 - then what's changed about him? He's bragged on live audio about grabbing a woman's pussy. That didn't phase the undecideds in 2016.
Do you think that 1/6 will change the undecided's opinion? - I don't, not at all. It's just more of the same - Trump is an immoral criminal. Old news.
IMO, Trump isn't our next President only if one of the following occurs: 1) He experiences a severe health issue or dies (I doubt this - looking at his close family members, they mostly seem to be very long lived - genetics suggest that Trump will live to 90+); 2) He decides not to run (unlikely); 3) He's convicted of a felony and is thus ineligible to run (maybe this happens); 4) Inflation is brought under control and American's are upbeat about the economy (I think that this is very unlikely as the war in Ukraine shows no sign of stopping any time soon).
Biden prevailed narrowly in 2020 because, I think, that anti-Trump sentiment was high. Arguably anti-Trump sentiment is similar going into 2024 - but this time, the economy is going to be terrible.
Even if 1, 2 or 3 occurs, although it won't be Trump as President, it'll be DeSantis or some other far-right clone; only 4 will change this outcome, IMO. I hope I'm wrong - but that's what I think.
