Speaking at a briefing for the British strategic advising company Global Counsel, Luntz said Trump’s advisers have “their heads up their asses” if they think Hunter Biden will be a winning issue for them.

“I’ve never seen a campaign more mis-calibrated than the Trump campaign. Frankly, his staff ought to be brought up on charges of political malpractice,” Luntz said.

“It is the worst campaign I’ve ever seen and I’ve been watching them since 1980. They’re on the wrong issues. They’re on the wrong message. They’ve got their heads up their assess…Your damn job is to get your candidate to talk about things that are relevant to the people you need to reach. And if you can’t do your damn job then get out.”
