This is a video that I never thought I’d see from a candidate not named Donald Trump, but Marco Rubio went on a tear this morning — mixing attacks on Trump’s record with deeply personal jabs. Rubio rightly calls out Trump for exploiting blue-collar workers and for failing in multiple businesses even as he constantly brags about his business success — but he also engaged in schoolyard taunts. He went after Trump for sweating in the debate and losing his cool in commercial breaks, and implied that Trump was concerned he’d wet his pants.


And Rubio was just getting warmed up. He then read Trump’s incoherent, misspelled post-debate Twitter rant, and finished with this kicker — claiming that Trump “must’ve hired a foreign worker to do his tweets.” Watch the whole thing:

At this point, it’s pretty clear that Rubio and Ted Cruz have a choice — lose with dignity or punch back twice as hard. They’re choosing to punch back, and as much as I hate to see GOP politics degenerate to this level, I think on balance it’s the right call (though the pants-wetting comment was too far). We are now living in the world that Trump made, and we’ll see if Trump can keep winning if his opponents start playing by his rules.
