Mr. Speaker, can I give you a bit of advice about the meeting this morning with Donald Trump?

Never let your mouth write a check your rear end can’t cash, Mr. Ryan, or as I call you, Ryan-O, as in Republican In Name Only.

Yes, yes, you’re the “leader” of the national Republican party, but the problem is, your party no longer exists. It was demolished by the guy you’re meeting with today — and 11 million or so of his voters (so far).

You and your pals Willard and Reince and the Bushes all had your chances — and you blew it. Didn’t see your name on the primary ballot in March, nor Mitch McConnell’s, the Turtle who’s coming out of his shell today to meet Trump.

Meet the new boss, most assuredly not the same as the old boss.

Look at it this way, Mr. Speaker: last month Trump got 386,290 votes in the GOP primary in Wisconsin, and he lost. In 2014, in the general election, all you could manage in your own district was 182,316. In 2012, you couldn’t carry your own state.

Last month, Trump won your home, Rock County, with 10,264 votes in the GOP primary. Yes, I know you and the rest of the Wisconsin RINOs adopted Ted Cruz at the end there, but let’s face it, you and your TPP free-trade neo-con open-borders masters hate the Canadian almost as much as you loathe Trump.

But if you add up Trump’s and Cruz’s votes in your home county, the two anti-Ryan-O’s got 78 percent of the vote.

This is why I say to you, Mr. Speaker, treat him with respect. Call him “Mr. Trump.” You might even think about kissing his gluteus maximus, you know, the way you’d jump to attention if Tom J. Donohue from the Chamber of Commerce wanders over from K Street and yells “Jump!” and you yelp, “How high, Mr. Donohue?”

But out here we don’t care about your stretch limos and your symposia and your phone calls from Willard Mitt Romney. The Wall Street Journal editorial page? Here’s a quarter, call someone who cares. As for your third-party fantasy — are you kidding? What did Kristol et al. call Romney after they met with him — “stale?” Talk about an understatement.

And Romney had the nerve yesterday to demand that Trump release his taxes. You know what, someone told me once that Mitt never even paid any taxes for 10 years. It was someone just like yourself, a Beltway lifer who became a multimillionaire in public service: Harry Reid.

I don’t know you, Mr. Speaker. But I do know the guy who’s trying to Eric Cantor you in the primary Aug. 9 — his name is Paul Nehlen. Call me small-minded, but when I see a candidate whose arms are covered with tattoos, generally speaking I cross the street to get away from him.

In Nehlen’s case, I’m willing to overlook the arm graffiti. I’ve had him on my show twice to raise money. How much have you got, $7.6 million? Wow, no wonder you let Mr. Donohue and the open-borders crowd scratch your stomach after they tell you, “Roll over, Paulie! Be a good dog.”

Do the right thing today, or we’ll give you the old Tom Foley. You don’t have to go home, but you can’t stay here.
