Any Republican including Haley would win vs Harris, Lackawanna county flips if harris is the nominee, I would expect massive swings among non-college whites towards Haley if Harris were the nominee, Biden with his working class aura managed to win a lot of these voters, not clear how Harris would.
You're just assuming that. You don't know that for a fact.
In the primaries, general election polling found Biden doing the best with these types of voters out of all the democratic candidates.
Um, OK. You don't know what will happen in 2024. You just assumed that Haley would do better than Harris among white working class voters. You don't know that.
Also, Nikki Haley isn't going to win the 2024 GOP primary anyways.
