WOW! Far as I know Trump has moved his residency to Florida from New York. He's a snowbird so it's no biggie most of 'em do it eventually.
Trump has used the absentee voting system in at least three elections: Trump voted by mail during New York’s mayoral election in 2017, cast an absentee ballot during the state’s midterm election the following year, and again used a vote-by-mail ballot in Florida’s primary election in 2020. (Snopes)
But I'm not sure I buy the bit about voting in Florida's primary... Did we have a Republican primary? He can't vote in the Democratic one and the one for candidates other than president isn't until August.
It's high past time that we start electing Americans to congress and the presidency who put America first instead of their political party. For way too long we have been electing Republicans and Democrats who happen to be Americans instead of Americans who happen to be Republicans and Democrats.
