MILWAUKEE — Just as they did in the Republican debate two weeks ago, Jeb Bush and Marco Rubio are circling each other, prepared to strike.

Hours before another debate Tuesday night, Rubio’s campaign released a video mocking the former Florida governor for his recent attacks on the current Florida senator, citing the praise that Bush once heaped upon his former protégé.

“I’m a huge Marco fan,” Bush is seen saying in the ad (twice).

The Rubio team released the video shortly after The New York Times reported that Bush allies are “privately threatening a wave of scathing attacks” on Rubio regarding items like his missed votes in the Senate and his chance of winning a general election.

Rubio and aides said they expect attacks because of his rise in the polls, past Bush but behind Donald Trump and Ben Carson. The campaign says the new video is designed to show what Bush said about Rubio before he “started the phony attacks.”

Bush himself raised the missed Senate votes during the Oct. 28 debate in Boulder, Colo., telling Rubio that “when you signed up for this, this was a six-year term, and you should be showing up to work.”

Rubio, saying that many senators miss votes when they’re running for president, told Bush: “The only reason why you’re doing it now is because we’re running for the same position, and someone has convinced you that attacking me is going to help you.”

The Bush-Rubio dynamic, the battle of Florida, will be one of the things to watch in Milwaukee.
