It is longer than 90 days to the general election, BUT it is within 90 days of Florida’s Primary to be held in August.
If you read the letter, you will find that Florida has a nasty knife up it’s sleeve -— if they can’t eliminate an illegal voter from the rolls, they will continue to identify illegal voters, identify if they actually vote, and then prosecute them for illegal voting.
I would assume that Florida will post a notice at the polling place that illegal voters will be prosecuted, and mention the penalties -— and the DOJ will go ballistic, accusing Florida of “voter suppression”.
Florida already had their Presidential Primary back in January or Feb didn’t they ?
