Election 2016: Colin Powell And 8 Other Republican Leaders Who Hate Donald Trump

Donald Trump claims to have expanded the appeal of the Republican party. That might be true — a record number of voters turned out for the GOP primaries — but many members of the party's old guard have voiced their displeasure with the controversial businessman.

Former Secretary of State Colin Powell is the latest Republican leader with disparaging things to say about the GOP nominee, calling Trump a "national disgrace" and "an international pariah." Powell joins a staggering large list of GOP stalwarts who have come out against their party's nominee.

Of course, Powell did not mean for his comments to go public. The criticisms were contained in around 30,000 leaked emails on Wednesday that were stolen from the retired four-star general and given to DCLeaks.com by unnamed hackers, according to USA Today.

Though Powell may have not made the comments publicly, he is far from the first to speak out against Trump.

Here are 8 other Republican leaders who oppose Donald Trump:

Mitt Romney

The former Massachusetts governor and 2012 GOP nominee is no fan of Trump. Romney gave a speech in March criticizing Trump and urging primary voters to throw to support behind someone else. Romney attacked Trump for his business failures, lack of experience and lack of civility in his campaign.

"I’m far from the first to conclude that Donald Trump lacks the temperament to be president. After all, this is an individual who mocked a disabled reporter, who attributed a reporter’s questions to her menstrual cycle, who mocked a brilliant rival who happened to be a woman due to her appearance, who bragged about his marital affairs, and who laces his public speeches with vulgarity," Romney said, later adding, "I’m afraid that when it comes to foreign policy he is very, very not smart."

Ted Cruz

Trump's most formidable challenger in the primaries, Texas Sen. Ted Cruz, has never come around on the GOP nominee. The two traded many barbs on the campaign trail, with Cruz calling Trump a "pathological liar."

"He doesn't know the difference between truth and lies," Cruz said in May. "He lies practically every word that comes out of his mouth. And he had a pattern that I think is straight out of a psychology textbook. His response is to accuse everybody else of lying."

Cruz further demonstrated his disdain for Trump by taking the stage at the 2016 Republican National Convention in July and telling voters to "vote their conscience," the clear implication being that a vote for Trump would be morally indefensible.

John Kasich

Ohio Gov. John Kasich tried his best to take the high road in the primaries, but he was no match for Trump. Though the swing state governor finally admitted defeat in June, he has not thrown his support behind the GOP nominee. During the RNC, Trump's campaign attacked Kasich for not showing up to speak. Kasich instead promised to focus his energy helping down ballot Republicans win congressional elections.

"Somebody who divides this country here in the 21st century, who's calling names of women and Muslims and Hispanics and mocking reporters, then says I didn't do it but he did do it, it's just not going to happen," Kasich said in November of Trump's chances to become the nominee. "And everybody needs to get over it and take a deep breath."

Jeb Bush

Trump dismantled former Florida Governor Jeb Bush during the primaries — the pair got into a series of infamous sparring matches during the debates with Bush famously telling Trump he could not "insult his way to the presidency."

It is no surprise Bush is not willing to be an ally now. In fact, the entire Bush family, including the most recent Republican president, George W. Bush, declined to attend the RNC this year.

Lindsey Graham

Unlike many Republican primary candidates, South Carolina Sen. Lindsey Graham never shied away from criticizing Trump's qualifications and temperament to be president. The outspoken senator has regularly urged members of his party to withdraw their endorsements and support from the GOP nominee. Graham even said the unthinkable for Republicans: that Democratic nominee Hillary Clinton was preferable to Trump.

"This is the most un-American thing from a politician since Joe McCarthy," Graham told The New York Times of Trump's claims Judge Gonzalo Curiel's Mexican heritage make him unfit to preside over the Trump University lawsuits. "If anybody was looking for an off-ramp, this is probably it. There will come a time when the love of country will trump hatred of Hillary."

George Will

The Washington Post columnist is perhaps the most respected conservative pundit in the country, but Will decided to "leave the Republican party" over Trump's nomination.

Before Trump's nomination, Will laid out the challenge for Republicans in no uncertain terms: "Were he to be nominated, conservatives would have two tasks. One would be to help him lose 50 states—condign punishment for his comprehensive disdain for conservative essentials, including the manners and grace that should lubricate the nation’s civic life."

Glenn Beck

The passionate and controversial conservative broadcaster has been vocal about his disdain for Trump, claiming he is not a true conservative.

"Donald Trump is the face of the GOP. Well, that makes us crony capitalists. It makes us wafflers. It makes us pretty racist," Beck said on his syndicated radio show in May. "It makes us big government guys. Just, you name it — it makes us that."

Charles and David Koch

The billionaire Koch brothers have been two of the biggest bankrollers of Republican presidential campaigns in recent election cycles, but not this year. In response to Trump, the Kochs have decided to focus their money on effort on congressional races to mitigate the damage Trump might do to the party down the ballot.
