Pasting my own comment, as I really think there was a reason for this.

"I’ve been seeing a trend for the last few years and I think it explains the shift that people have been pointing out in the Democratic party. The way in which many Democrats felt railroaded into Hillary in 2016, I think the same is happening to the Republican party, albeit more unknowingly. There is a not insignificant amount of Republicans who have been disenfranchised from voting red because that’s just what you do. It all comes down to the Republican party being split by the MAGA cult, with those Republican voters wanting to return back to the status quo of red vs. blue. Of course what they don’t realize is that the culture war that the conservatives have been imposing is what created this whole situation in the first place.

Anyway, this is where Dick Cheney comes in. Yes, a representative of that culture war that brought us here, but not a MAGA cultist. An endorsement from one of the most recognized Republicans is an attempt to move back towards the classical conservatism, away from the clamoring fervor that the Trump presidency put the country in.

That is to say, if the Green Party is meant to siphon votes from Democrats, The Classical Republican Dick Cheney is meant to appeal to the votes from Moderate Republicans and maybe convince some Republican voters who would have voted red “because that’s what you do”, to instead vote for Kamala.

This isn’t to say his endorsement of her isn’t damning and that the leaders of the Democratic haven’t been shifting away from the left. Just positing that like many of us, there’s a portion of Republicans out there who are just as tired."

I wrote this pre-election results. Can probably tell. But basically Tl;Dr Cheney is a classical conservative and his endorsement was an attempt to return to the status quo pre-MAGA, as a way to hopefully return to the Republican vs. Democrat split, instead of this 4 way split between leftist, liberal, conservative, and MAGA voters.

Obviously, that didn't sit that well with the Democrats and the leftists. I get where the campaign was coming from, I don't agree and it was a bad move, but I understand it.
