The latest news on this front comes from Washington Post:

A network of out-of-state political consultants, secret donors and activists with close ties to President Trump is behind an effort to change the Florida constitution to explicitly state that only citizens may vote in elections, a measure that would amplify the issue of immigration in the 2020 battleground state.

In recent months, organizers said they have collected nearly twice the signatures needed to qualify for the ballot next year — and more than any other ballot initiative in Florida state history, they said.

The exact legal effect the amendment would have remains unclear. While federal law explicitly bars noncitizen voting, the language in the Florida constitution — like that of many states — says that “every” citizen who is 18 may vote. The proposed amendment would change the language to say “only” a citizen may vote.
