Steve Lonegan, the New Jersey state director of Ted Cruz's defunct presidential campaign, called for a delegate revolt on Tuesday.

Lonegan told CNN he would not vote for Donald Trump or Hillary Clinton, and said "this is turning out to be a debacle." The former Republican senatorial candidate in the Garden State said Trump has a big problem if he gets under 80 percent of the vote while running unopposed.

"Our delegates have an obligation come July to do what's right for the Republican Party, not just anoint Donald Trump," Lonegan told CNN.

"Are you calling for a revolt?" interrupted CNN's Kate Bolduan.

"I would love to see a revolt," Lonegan answered. "And what I'm seeing right now, it's time for the Republican Party to get some backbone and stand up against this guy."

Lonegan said Courageous Conservatives PAC, the pro-Cruz super PAC for which he's a spokesman, has turned its attention down ballot because Republicans in Congress could have a big problem come November.
