As of October 29 at 10:07 AM, Republican voters have voted early or returned Vote-By-Mail ballots at a higher rate than Democrats in Florida. The Democrats picked up some ground, but are still 55K votes behind the Republicans. This is significant because in the 2016 general election Democrats turned out more voters in the early voting process and Republicans won huge on election day.
Early voting ends (for the most part) this Saturday (November 3rd). If the numbers stay similar to what they are now, it is a very good sign for Republican candidates.
