Conservative Rep. Justin Amash, R-Mich., is considering a Senate run if Democratic Sen. Carl Levin retires, according to a report in National Review.

Amash has told local activists he’s intrigued by a statewide run, per the conservative outlet. An Amash spokesman did not immediately respond to an email and voice mail message.

Levin, 78, has not said yet whether he will seek a seventh term, but his spokeswoman told the Lansing State Journal this month that she expects a decision “in the next few weeks.”

If he retires, Michigan Democrats expect a top official in the state will run in his stead. Wolverine Republicans are more concerned about their candidate prospects for the race — especially after Sen. Debbie Stabenow, D-Mich., walloped former Rep. Peter Hoekstra, a Republican, by 20 points last November.

Michigan GOP insiders were not surprised by Amash’s interest. Paul Welday, a Republican consultant in Michigan, said “there have been rumors to that effect for a while.”

“I think it’s very much still in the embryonic and discussion phases,” Welday added.

Amash, one of the most conservative members in the House, has had a contentious relationship with the GOP leadership. In December, he was booted from the House Budget Committee.

What’s more, Amash did not vote for Speaker John A. Boehner at the start of this Congress. Instead, he cast his ballot for Rep. Raúl R. Labrador of Idaho.

Welday said, given that Amash has been frozen out of House leadership, “he might figure he’s got nothing to lose taking his crusade statewide.”

Amash, 32, won his first term with 60 percent of the vote in 2010. He won re-election in November by about 9 points.
