Biden and Trump to visit Miami in last-minute Florida push

• Trump will visit the Miami-Dade County fairgrounds for a Sunday rally supporting Sen. Marco Rubio.

The intrigue: Trump won't be rallying for Gov. Ron DeSantis this weekend.

Why it matters: Democrats are deploying their biggest asset to the Sunshine State as the party faces signs of a growing red wave, which has pushed strategists to shift their messaging in the final midterm stretch.

• Meanwhile, Trump's visit serves as another example of the growing division between him and DeSantis, who the former president endorsed in 2018. The two are considered to be potential presidential rivals in 2024.

State of play: Crist and Demings are down in the polls, and they're probably hoping a visit from the president could fuel a voter bump come Nov. 8.

Yes, but: Biden's approval ratings are around 42%, per Five Thirty Eight — which could arguably be more of a liability than an advantage for Democrats, Axios' Hans Nichols writes.

What they're saying: University of North Florida pollster Michael Binder told the Palm Beach Post that Biden's visit might be "six months too late," because millions of Florida voters have already cast their ballots.

• "I do think it's important that Democrats don't just give up and give Florida away, because there are congressional seats that could be in play," Binder told the newspaper.
