That's.... Not how US elections work. Otherwise Hillary would've won 2016
Looking at the state results it doesn't appear that any state would've flipped blue if all third party voters excluding Robert Kennedy and Oliveros (libertarian) voters because they definitely would not have gone Harris went Harris. Even if you could the right wing 3rd party ones she only would've won 2 more states and still lost.
If we used the popular vote I definitely would've voted Harris, but as it is Trump was going to win my state by huge margins so I just voted who I really wanted knowing it made no difference. In races other than president I went Dem.
No, they really would not have.
At best if you generously count right wing third party voters too (like Robert Kennedy voters) she would've won two more states but that would not have won her the election.
