By 2050...

will partisanship remain the same and will we continue to go back and forth? Will Hispanics save the Republican Party for a generation? Will Democrats solidify just enough electoral votes to win every time?

It's hard to predict. In 1933, the GOP didn't know that they would be locked out of the Presidency (and, except for 1947-48, Congress) for another 20 years, and that several more years of the Depression, a world war, and the beginning of a nuclear arms race would ensue in the meantime. Then again, in 1977, many were proclaiming the GOP dead or dying (witness Henry Fairlie's book, The Elephant Graveyard / The Donkey Serenade: it had the support of barely 20% of Americans per identification, less than half the proportion who identified as Democrats; I'm sure few would have predicted that in 1980, the GOP would take the Senate as well as the Presidency.

I'd say about 50/50, but what do I know?

2020 being as close as it was suggests we will continue to have close presidential elections for some time.  The biggest opportunity to break out into a national landslide in the next generation would be a fiscally moderate Hispanic Republican running in a favorable economy (they could make IL/CA/NY close).

Wow, I didn’t know that part about of 1977. Would never have guessed considering Nixon had won a massive landslide a few years prior. Thanks.

Nixon didn't really bring anyone else in with him downballot in that landslide, so it was largely seen as a personal vote against McGovern at the time.  People forget that because both parties play to win at the national level, election outcomes inherently regress toward 50/50 in the long run (in the EC or in congressional seats, not necessarily in the PV).  It takes really exceptional circumstances to generate a long winning streak.
