the Spring Mountain Republican Women's club in Nevada weren't really prepared for this.

Speaking before several GOP women's groups who invited him to Las Vegas, Donald Trump launched into a profanity-laced tirade against President Obama and his administration's policies.

Among the bons mots, as you can hear in the amateur video above [originals here]:

-- Trump would deal with OPEC in order to lower oil prices just by being tough: "We have nobody in Washington that sits back and said, you're not going to raise that f—-ing price,"

-- Here's how he'd tell China he intends to slap a tariff on their exports: "Listen you mother——ers we're going to tax you 25 percent!"

He sprinkled obscenities throughout, including one not in the video, describing Iraq: "We build a school, we build a road, they blow up the school, we build another school, we build another road they blow them up, we build again, in the meantime we can't get a f---king school in Brooklyn."

Oh, and apparently he believes that the idea that Iraq could become a democracy is a joke. Which makes you wonder about his audience of former George W. Bush devotees -- especially when they applaud this loudly.

Now, I understand that, you know, when in Rome, blah blah blah. But you gotta wonder if Franklin Graham or the rest of the Religious Right still think Trump is a good horse to be backing, you know what I mean? Not to mention the Spring Mountain Republican Women's Club.
