Donald Trump’s proposal to ban Muslim refugees from the homeland has caused such a furor that his own county Republican leader considered booting him from the party, The Post has learned.

Under New York state election law, the county chairman of a political party has the power to “disenroll” a member for bringing disrepute or whose values are counter to the party’s.

But Manhattan Republican county chairwoman Adele Malpass rejected calls to bounce Trump.

“Mr. Trump has made many statements about immigrants, Muslims, women and other topics which are diametrically opposed to the principles of the Republican Party. This is not what the Republican Party stands for or the values of the Committee which I chair,” Malpass said.

“However, I believe in the power of democracy, and I will let the voters decide Mr. Trump’s political future,” she said.

A Manhattan GOP insider added, “She didn’t want to give Trump the excuse to run as a third-party candidate.”

The source also said Malpass questioned whether a party leader should have such extraordinary power to bounce a registered party member — let alone a candidate for president — over a controversial policy dispute and free speech issue.

A Bloomberg Politics poll released Wednesday found that nearly two-thirds of Republicans support the Trump Muslim refugee ban to protect the nation from terrorism, as did 37 percent of all respondents.

But Joe Lhota, the Republican Party’s candidate for mayor in 2013, ignited the “dump Trump” discussion by urging Malpass to boot The Donald from the GOP.

“I think Adele Malpass should take a look at this and actually throw Donald Trump out of the Republican Party, which it can do under state law, “ Lhota said Tuesday night on NY1.

Lhota said Trump has a right to speak his mind under the First Amendment. But he added, “He doesn’t have a First Amendment right to be a Republican. Republicans ought to take a stand.”
