Donald Trump's hostile takeover of the Republican Party is a done deal, and a landslide win for him in New Jersey's primary Tuesday is a sure thing.

No matter what happens in November, this is going to leave an ugly stain on the party.

If you are Muslim, the Republican Party now wants to use the machinery of government to discriminate against those of your faith. If you are Mexican-American, the party has just embraced a man who has slandered your countrymen as rapists and criminals. And if you are in either group, Trump just declared you unfit to sit as a judge on any case that involves him. Because it is you who are biased, inevitably, thanks to your race or religion.

The damage to the Republican brand doesn't end with Muslims and Mexicans. Because many millions of Americans who pass this new test of ethnic and religious purity are appalled as well.

African-Americans are no doubt most alert to the wreckage this brand of thought leaves in its wake. But America is full of ethnic and religious groups that can remember when the finger was pointed at them. It is unnerving to hear Holocaust survivors say they hear an echo of fascism in the ranting of the new Republican standard-bearer.

Put aside the bigotry, and you find more reasons to be shocked and appalled. He would abandon the effort to contain the spread of nuclear weapons, and has not remotely prepared himself to be commander in chief. His promise to impose 45 percent tariffs on Chinese imports would ignite a ruinous trade war. His bluster about pulling back from NATO can only encourage Russia to be more aggressive and reckless. His plan to abandon the fight against climate change would cripple the global effort just as it gains a foothold.

Trump would hand out tax cuts to the rich, and abandon efforts to contain entitlement spending. He would kill Obamacare, depriving 20 million people of coverage with no hint where they could go next.

It is flat-out depressing that the bulk of Republican voters are embracing this man, and to see party leaders fall in line, one by one.

Gov. Christie Whitman is a brave exception to the rule. But where are the others?
