Donald Trump said this week that if the GOP doesn't "man up" and support everything he says, he will freeze out the RNC and run his campaign alone.

Trump was angry that so many Republicans condemned his attack on the Hispanic judge and publicly opposed his ban on Muslim immigration. He said Republicans should either support him or "keep quiet."

Washington Times:

“You can’t make this up sometimes,” House Speaker Paul D. Ryan said at a press briefing Thursday on Capitol Hill.

Mr. Trump’s admonition came after several weeks of chiding from fellow Republicans who decried his proposal for a temporary ban on Muslims entering the U.S., and who said his attacks on a federal judge’s ethnicity were unbecoming. Mr. Ryan had called it “the textbook definition of a racist comment.”

“The Republicans, honestly, folks, our leaders, our leaders have to get tougher. This is too tough to do it alone. But you know what? I think I’m going to be forced to. I think I’m going to be forced to,” Mr. Trump said on Wednesday.

“Our leaders have to get a lot tougher. And be quiet. Just please be quiet. Don’t talk. Please be quiet. Just be quiet — to the leaders. Because they have to get tougher. They have to get sharper. They have to get smarter. We have to have our Republicans either stick together or let me just do it by myself. I’ll do very well,” Mr. Trump insisted.

GOP observers said Mr. Trump is playing with fire.

“Most people respond better to charm and subtle persuasion than they do to threats, and most victories are won by team efforts versus lone wolves,” said Fred Malek, a White House veteran who serves as finance chairman of the Republican Governors Association. “Trump certainly knows this from his success in business, and why would he think it’s different in politics?”

Mr. Malek said voters want Mr. Trump to “step up and be an inclusive leader.”

But the maverick candidate began his campaign on the other side of the spectrum, accusing Mexico of sending “rapists” and other bad elements of its society to the U.S.

His approach appeared to work in the GOP primary, with his criticism of fellow politicians as “stupid” and “all talk, no action” earning him fans from alienated conservatives and moderates alike.

That has led to an uneasy relationship with the Republican National Committee, as well as GOP lawmakers nationally who’ve had meltdowns over his brash brand of politics, concerned that he is tarnishing the party and its chance of retaining control of Congress in the November election.

This week Maryland Gov. Larry Hogan and Richard Armitage, who served as deputy secretary of state in the George W. Bush administration, announced they were jumping ship and couldn’t support Mr. Trump.

Trump is in his own universe when it comes to his toxic, bigoted comments. He believes that the "stronger" his insults, the more support he will get.

But he doesn't realize, or care much, that Republican politicians have to exist in a different universe - the real world where making racist comments actually has a downside. He can't expect support for his outbursts, nor can he expect GOP politicians to "keep quiet" when silence, to many voters, means assent.

As big as the disaster that is looming in November for Trump and the GOP, it would be nothing compared to what would happen if Trump booted the party from his campaign. Already underfunded with little organization, he would be buried by the Democrats in a disaster unprecedented in American political history.
