 For the greatest president that's ever lived, and that's Donald J. Trump. Donald Trump has become the official Republican presidential nominee after receiving the votes of enough delegates at the Republican National Convention. Trump has been the presumptive nominee for months, but it was the vote of RNC delegates in Milwaukee that made it official. Trump hit the necessary threshold with votes from his home state of Florida. The move comes just minutes after Donald Trump selected Senator J.D. Vance of Ohio as his Republican running mate.
