From 2000-2050, which party will control the presidency for the most time?

2030: Senate flips R

This would be an absolute bloodbath, especially if Democrats win back the Senate next year and make even more gains in 2024. I could see the GOP picking up MO, IN, WV, MT, PA, MN, MI, WI, ME and maybe even FL and ND. TX and MS would probably be vulnerable as well, assuming the Ds won those states in 2024.

Yes.  It could be something like +12R in one cycle.  But the weird part is that almost all of the currently R-held seats in that class could be D-held by 2036/42, after half the currently D-held ones flip back.  It's the most "behind the times" senate map, and between Trump's approval and the likelihood that 2024 is either Trump's 8th year itch election or a 1st term Dem incumbent seeking reelection, looks likely to stay that way for a while. 

Why WY and NE, though? Even TN might be a stretch IMO, although I agree on the others.

Thinking NE and maybe TN, with WY being the only one to stay solid R.  Basically Omaha and Nashville eventually start acting like Jefferson County and Shelby County did in the AL special, making Dems (barely) viable statewide again.  I don't think it will all happen next year, though.

My guess:

2020 - GOP (very close, and they lose the PV by even more than in 2016)
2024 - DEM (landslide)
2028 - DEM (landslide)
2032 - DEM (close, but far from a nailbiter)
2036 - GOP (close)
2040 - GOP
2044 - DEM
2048 - DEM

So the Democrats.

I pretty much agree with this. Though I think its possible that the GOP doesn't rebound by 2036 and we see the Democrats control the presidency for a 16-year stretch from 2025-41 instead.

2028: Incumbent Vice President wins by a close margin
2032: Republican wins by comfortable margin
2036: Incumbent Republican wins by the same margin
2040: Democrat wins by extremely close margin, could possibly lose popular vote
2044: Democrat wins by more comfortable margin, still close
2048: Republican wins in a landslide
