WATCH: Trump unifies the GOP by viciously trashing New Mexico's Republican governor

A lot of political observers assumed that Donald Trump would take on a more "presidential" tone once he clinched the Republican nomination for president. So far, those assumptions have turned out to be very, very wrong.

In his latest offense, Trump decided to fire up the crowd at a campaign rally in Albuquerque by taking shots at New Mexico Gov. Susana Martinez, who just happens to be a Republican.

"Since 2000, the number of people on food stamps in New Mexico has tripled," Trump said in making his case against Martinez. "We have to get your governor to get going, she's gotta do a better job. Your governor has got to do a better job. She's not doing the job. Hey, maybe I'll run for governor of New Mexico, I'll get this place going!"

Trump then ripped Martinez for allowing Syrian refugees to be resettled in New Mexico, even though he acknowledged that governors don't really have a choice about whether their state will accept refugees since it's the federal government's call.

"They say governors have no choice, if I'm governor, I have a choice, believe me," Trump boasted.

Martinez, who took shots at Trump this past fall while campaigning for then-presidential hopeful Marco Rubio, pointedly declined to attend Trump's rally this week. In the wake of Trump's comments, the governor's office said that "she will not be bullied" into supporting Trump.
