Cindy McCain, the wife of the late Republican Sen. John McCain, decried the current state of politics one year after his death Sunday — as she said all the people running for president are “good candidates.”

Appearing on CNN Sunday — the one year anniversary of her husband’s death from brain cancer at the age of 81 — the 65-year-old said her late husband would be “very disappointed” by the nation’s nasty political climate.

“He would be saddened by the digression that these conversations and these debates have taken, and also saddened that we’re so disoriented within the world right now,” McCain said, alluding to the ​president’s ​leadership.

Asked if Democrat Joe Biden would make a good president, she demurred — indiscriminately saying that all the candidates had their pros.

“Well, I think we need to let the process work,” ​she said Sunday on “State of the Union.” “I think all the candidates are good candidates, they represent different views, they represent different ideas, this is going to be a tumultuous election for many, many reasons.

“So I look forward to hearing from all of them and I look forward to seeing the process work,” she continued. “It’s a lot of fun.” ​

T​rump, who made no secret of his dislike of John McCain, said he didn’t consider the former Navy pilot — who spent more than 5 years as a prisoner of war in Vietnam — a hero.

“I like people who weren’t captured,” Trump said during the 2016 campaign.

Trump continued to hector McCain even after his death for casting the critical vote in 2017 to end the Republicans effort to repeal and replace ObamaCare.

At McCain’s funeral last year, Biden opened up his eulogy with the line: “My name is Joe Biden. I’m a Democrat and I love John McCain.”

On Sunday, Biden chimed in again.

“One year ago, we lost a political giant, and a genuine American hero – my friend, my frequent opponent – John McCain. We still feel keenly his loss in our public life,” Biden said in a statement.

“John lived by a code that sometimes seemed to be from another era, where honor, courage, character and integrity mattered. But in truth, John’s code was ageless – an American code, grounded in decency and basic fairness and an intolerance for the abuse of power.”

“A code neither selfish, nor self-serving,” Biden added.

​McCain, who planned his funeral, ensured Trump wouldn’t be invited and had former Presidents Obama and George W. Bush deliver eulogies.

Trump, in France for the G-7 meeting, hasn’t acknowledged the McCain anniversary.
