Lewandowski, in a follow-up interview with POLITICO, said he's weighing two factors in his decision whether to run: Fundraising numbers from his would-be primary opponents and the direction of impeachment proceedings in the House.

He said he thinks Trump's potential support would allow him to jump into the race late.

“I think if I were to get in the race, I have the president's endorsement,” he said. “If I get in this race, I'm going to win the Republican nomination.”

If the impeachment effort fails, Lewandowski said he might get in the race afterward, even if that means it's next year. The filing period in New Hampshire isn’t until June, and the primary is just under a year away.

“I'm not going into the White House” to work for Trump, he said. “I have no desire to go and become a government employee. But if this fake witch hunt gears up to try to impeach the president and there is value for me to continue to be a high-profile surrogate for the president over the next many months, I will do that.”

Lewandowski has used Heath's show almost exclusively to talk about politics, including his own plans. Trump also called into the show in mid-August, partly to talk up a potential Lewandowski Senate bid.

In an interview with POLITICO, the radio host said it seemed apparent Lewandowksi is not going to run. He had expected Lewandowski to announce on his show in the past week or two, though Lewandwoski has also said he would announce on "Fox & Friends" and potentially during his testimony in front of the House Judiciary Committee.

"It shows you the ripple effect of the impeachment inquiry back in New Hampshire," Heath said.

Lewandowski, who has been floating a bid for Senate since September, did not immediately respond to a request for comment. His trial balloon triggered a backlash among some top New Hampshire Republicans.

The state's Democratic Party has been closely monitoring Lewandowski's public statements since he began floating a run.

“With or without Corey Lewandowski, New Hampshire Republicans are in a nasty primary among candidates all committed to protecting a corrupt President determined to take away health care from thousands of people in the Granite State," party spokesman Joshua Marcus-Blank said.
