Trump tried to register to vote in Florida while claiming his “legal residence” was in another part of the country — Washington, D.C. — according to Florida elections records. The September 2019 registration application listed Trump’s legal residence as 1600 Pennsylvania Ave. NW, the location of the White House. That created a potential problem for Trump: Florida law requires voters to be legal residents of the state. A month later, Trump resubmitted his application to use a Florida address and in March he voted by mail in Florida’s Republican primary.
