1) Not wrong about anything.
2) Politicians can and do change their views on things all the time. Trump has a long history of flip flops (but so do ALL politicians).
3) Kamala Harris has not been the President, so any agenda she sets for herself going forward after she wins (which she will) is hers. She doesn't own Biden's agenda.
4) Yes, she and Trump share some views. Big deal. Harris could have exactly ALL the same views as Trump, and I'd still vote for her because she's not a criminal, sexual abuser, autocrat, POS human being.
5) Yes, Rasmussen is a horrible polling source, skewed heavily towards Republicans. You shouldn't count on polling anyway, but if you're looking for a poll that is at least a little bit accurate, it's not Rasmussen.
6) You are wrong about predicting Trump as the winner. The 13 Keys clearly have Harris as the winner, and she WILL win. There are so many headwinds against Trump...he's old...he's stupid...the abortion issue is an albatross around his neck...he's a convicted felon who will soon be sentenced, and he has more legal issues ahead; Americans are tired of that nonsense. BUT again, it's the 13 Keys that really matter, and Harris is the predicted winner...and she WILL win.
The ironic and hilarious thing about Trump (and personally I would have rather NOT have had to deal with him all these years now) is that the pushback against him has done so many things that progressives have wanted that would NOT have happened yet if it hadn't been for Trump's political existence:
Washington Redskins name changed
Cleveland Indians name changed
Confederate Battle Flag properly demonized and prohibited from NASCAR events and many other places
Confederate statues and monuments removed
First woman President about to be elected
