United States President Barack Obama is getting down into the nitty-gritty as he campaigns in Florida for Hillary Clinton. Obama is urging Clinton supporters at a get-out-the-vote rally in Miami to take advantage of the opportunity they have to vote early, before Election Day next Tuesday. The rally is the first of two that Obama is headlining in Florida on Thursday. He has another later in the day in Jacksonville. A victory there would almost assure Clinton the presidency.
