Donald Rumsfeld dismissed reports that George H.W. Bush plans to vote for Hillary Clinton by pointing to the former president’s age.

“He’s up in years,” said Rumsfeld, a Trump supporter, on MSNBC on Thursday.

“He obviously comes from a totally different cut than Donald Trump.”

Bush is 92. But Rumsfeld is 84.

Kathleen Kennedy Townsend, daughter of Robert Kennedy, claimed on Facebook this week that the Republican former president and former Republican National Committee chair is supporting Democrat Clinton.

“The President told me he’s voting for Hillary!!” wrote Townsend, with a picture of her posing with the 41st president.

Rumsfeld served in the George W. Bush administration as secretary of defense.

In June, Rumsfeld told The Post he found it easy to back Trump over Clinton. “I don’t even find it a hard decision,” he said.

Pointing to Clinton’s mishandling of classified information and ethical lapses, Rumsfeld said the Democratic presidential candidate’s conduct has been “disqualifying.”
