After largely ignoring Marco Rubio for months, Donald Trump suddenly can’t heap enough criticism on the Florida senator. Trump tweeted that Rubio’s middle name was “amnesty” on Tuesday; he called Rubio a “lightweight” in South Carolina on Wednesday; and he offered up some physical observations about the senator on msnbc’s “Morning Joe” Thursday.
“[He] has the worst voting record in the United States Senate,” Trump said. “He sweats more than any young person I’ve ever seen in my life.”
Then, Trump criticized Rubio again Thursday night, slamming the senator’s Iowa event on Twitter.
Just watched @marcorubio on television. Just another all talk, no action, politician. Truly doesn't have a clue! Worst voting record in Sen.

Now, there’s nothing new about Trump dumping on another candidate. It’s kind of all he does. What was surprising was that Rubio, who has normally avoided these kinds of spats, responded with vigor.

“He had a really bad debate performance last week,” Rubio said in a appearance on Kentucky Sports Radio Thursday. “He’s not well-informed on the issues. He really never talks about issues and can’t have more than a 10-second soundbite on any key issue. And I think he’s kind of been exposed a little bit over the last seven days, and he’s a very touchy and insecure guy and so that’s how he reacts, and people can see through it.”
This marks the first time that Rubio and Trump have gotten into an extended back-and-forth and, in many ways, it makes sense for both of them. Here are some theories as to why their long détente might finally be breaking down.
Why would Trump go after Rubio?
1. It gets him out of other fights.
Trump’s default strategy is to go on offense; the only thing that changes is the target. If one attack doesn’t go as planned, he shifts his attention elsewhere quickly. One typical example: In July, Trump drew his first real push-back from Republicans after he argued that Sen. John McCain was “not a war hero” because he was captured in Vietnam. Rather than apologize or dwell on the episode, Trump gave out Sen. Lindsey Graham’s phone number in a speech. Boom, McCain fight is old news.
Last week, Trump’s principle antagonist was Carly Fiorina, with whom he clashed repeatedly during the GOP primary debate making deragoatory comments about her appearance to Rolling Stone magazine. Unlike prior fights with his rivals, Trump – who has well-documented issues addressing women — seemed uneasy going up against Fiorina, who earned a bump in the polls from the debate while Trump’s lead shrank.

Fiorina, who on Thursday approvingly quoted National Review editor Rich Lowry’s suggestion that she had castrated Trump at the debate, clearly wants to keep up the feud. Trump, on the other hand, is suddenly scrapping with Rubio along with Fox News and Club For Growth. Chances are, it’s not a coincidence.
2. Rubio may be the best target.
For one, Fiorina and Carson have their own troubles to worry about. They’re outsider candidates who are only now getting the kind of scrutiny that some of the more experienced contenders (like Rubio) are used to. Fiorina’s checkered business record is under the microscope along with remarks she made in 2013 supporting a requirement that Americans buy health insurance, a core feature of Obamacare. Carson is now dealing with stories about his attitudes towards Muslim-Americans that raise questions about whether he’s mainstream enough for a general election.
