Donald Harris vs. Kamala Trump

[Schiff for Senate]

I think you made a mix-up with the names...
It's Donald Trump, not Kamala Trump, and Kamala Harris, not Donald Harris.
I don't know Don Harris and Kammi Trump, and I don't think either will run for president in 2024.

Probably similar to 2020, though I think Kamala Harris might do better. I think she holds on to the states of AZ, GA and NV because of January 6 - possibly even more suburbanites might break away from the GOP if Trump is nominated for a third time, especially after the raid on the capitol by Trump's crazed supporters.

If 2024 is a good Democratic year, Kamala Harris might flip North Carolina as well (especially if Roy Cooper's her running mate), and if it an exceptionally good year for them and the Biden Administration is highly popular, possibly even Florida.

If the Biden administration is generally unpopular, I can see Wisconsin and perhaps Arizona flipping red (with Trump on the ballot I don't think the Atlanta metropolitan area will start reversing its Democratic trend, especially after January 6), though neither seems likely. I think Pennsylvania and Michigan will most likely stay blue unless 2024 somehow becomes a great year for the GOP (i.e. Biden/Harris are unpopular and/or the economy is lagging, etc.), which currently appears quite unlikely, and may stay blue even then.
