Miami Dade is such an unpredictable wildcard that I have no clue. We need to see how Rubio and DeSantis do there in 2022 to have any clue what the county's political trajectory is. I stand by the previous post I made that's quoted below about whether Trump could have done better in Miami Dade or not.
Hard to say based on current information. We won't know the answer to this until we see whether the GOP can continue building on its gains there. If the GOP does gain to the point where they win the county in an upcoming election, then it probably was a realistic possibility if Trump ran a better campaign. However, if the county swings back to the Dems and Trump's performance proves to be an outlier, then he probably did the best he could have done. Either scenario is possible. We'll see how DeSantis and Rubio do here in 2022.
I am still amazed to see people speculate on this county with such certainty. People keep saying things like "This county will FOR SURE swing back Dem! Trump did the best any Republican can do and the Cuban vote is maxed out!" after this county just delivered an unbelievable result literally nobody saw coming in 2020! People who predicted Trump getting 46% would have been called insane trolls! There is no reason to be sure that the county will not become more GOP. I would agree that the county is unlikely to flip, but its certainly a possibly since that would only require a 7 point swing, which is nothing compared to the 22 point swing from 2016-2020.
Dade is unique and weird enough that it could go R+10 in 2024 in the same election Biden wins GA, NC, WI, MI, PA ,AZ, NV and TX from additional suburban gains. Its mix of Cubans/South Americans is just completely different than Mexicans in TX/AZ/NV and no other county in the country is like it.
By this logic it could also go D+22
