The list of Republicans supporting Hillary Clinton is still growing. For months, we have been keeping track of all of the GOP politicians, administration officials, business leaders and donors who have crossed over to back Clinton over Donald Trump.

The most recent high-profile announced was from former secretary of state Colin Powell. "General Powell said at a meeting of the Long Island Association that he would be voting for Hillary Clinton," spokeswoman Peggy Cifrino said in late October. Powell added in a brief interview with The Post's Karen DeYoung that he picked Clinton "because I think she’s qualified, and the other gentleman is not qualified.”

Powell's support isn't much of a surprise, given his support for President Obama in 2008 and 2012 and clear distaste for Donald Trump. In his leaked emails from last month, Powell also appeared to be talking over the best time to announce his support for Clinton.

But at least it's official now. And Powell is now the third Bush Cabinet official to support Clinton.

Below is that list as it stands:

Former presidents (1?)
  • George H.W. Bush (?) -- Kathleen Kennedy Townsend said in a Facebook post that Bush told her this in-person. The president's office isn't confirming it, but she stands by it. "That’s what he said," she told Politico
Members of Congress (1)
  • Rep. Richard Hanna (N.Y.), a moderate Republican who is retiring this year, told Syracuse.com that he will support Clinton and that Trump is unfit to lead. He cited Trump's criticism of Khizr Khan. "I think Trump is a national embarrassment," Hanna said. "Is he really the guy you want to have the nuclear codes?"

  • Richard Armitage, deputy secretary of state and adviser to Ronald Reagan and George H.W. Bush — Trump "doesn't appear to be a Republican, he doesn't appear to want to learn about issues. So I’m going to vote for Mrs. Clinton."
  • Brent Scowcroft, chairman of the President's Intelligence Advisory Board and adviser to three previous Republican presidents — "The presidency requires the judgment and knowledge to make tough calls under pressure. ...

  • Frank Lavin, former Reagan political director and ambassador to Singapore — "It might not be entirely clear that Hillary Clinton deserves to win the presidency, but it is thunderingly clear that Donald Trump deserves to lose. From this premise, I will do something that I have not done in 40 years of voting: I will vote for the Democratic nominee for president."

Foreign policy leaders (3)

Business leaders/donors (8)
Political operatives (10)
  • David Nierenberg, finance chairman to Mitt Romney's 2012 campaign
  • Mark Salter, former top adviser to John McCain — "Whatever Hillary Clinton’s faults, she’s not ignorant or hateful or a nut. She acts like an adult and understands the responsibilities of an American president. That might not be a ringing endorsement. But in 2016, the year of Trump’s s campaign, it’s more than enough."
  • Sally Bradshaw, former top Jeb Bush adviser, told CNN that she had left the Republican Party to become an independent because of Trump's presence at the top of the ticket — and that if the race were close in her home state of Florida this fall, she would be voting for Clinton. "As much as I don't want another four years of [President Barack] Obama's policies, I can't look my children in the eye and tell them I voted for Donald Trump."
  • Ana Navarro, Florida GOP consultant and frequent CNN guest
  • Maria Comella, former spokeswoman for two of Trump's top backers, Chris Christie and Rudy Giuliani — "Instead of speaking out against instances of bigotry, racism and inflammatory rhetoric whether it's been against women, immigrants or Muslims, we made a calculus that it was better to say nothing at all in the interest of politics and winning elections."
  • Kurt Bardella, former top aide to Rep. Darrel Issa (R-Calif.) and ex-spokesman for Breitbart News -- "A big reason why I decided that Hillary Clinton is the candidate who I’m voting for -- the first Democrat I’m voting for in my life -- is because this is a time where what’s going on is much bigger than partisanship, bigger than Republican or Democrat, or single issues that traditionally these campaigns are about."
  • Mike Treiser, former Mitt Romney aide — "In the face of bigotry, hatred, violence, and small-mindedness, this time, I’m with her.”
  • Craig Snyder, former chief of staff to then-Republican Sen. Arlen Specter (Pa.) and an ex-colleague of former top Trump adviser Roger Stone and current top Trump adviser Paul Manafort.
