GRAND RAPIDS, MI Despite glowing praise of U.S. Rep. Justin Amash's two-year tenure in Congress, one libertarian blogger thinks he should stay out of the race for retiring Michigan Sen. Carl Levin's seat.

Ron Davis, writing on the libertarian blog United Liberty, urges Amash to stay planted in his 3rd Congressional District because he'd have an uphill battle.

Amash has not said whether he'll run for Senate, but earlier this week indicated he was "certainly open" to the possibility.

A number of heavy-hitting prospective Republican candidates have been named since Levin's March 7 announcement he would not seek a seventh term.

They include West Michigan politician and former Secretary of State Terri Lynn Land, U.S. Rep. Mike Rogers and Scott Romney, older brother of Mitt.

Davis, writing on Amash for United Liberty, started his column with effusive praise for the "actively and openly accountable" sophomore congressman from Cascade Township.

"I wish my Congressman were more like Justin Amash," Davis wrote. "I wish every member of Congress were more like Justin Amash."

Still, Davis contends, multiple factors work against an Amash Senate run. He pointed to 2012's race against "self-funded" Democrat Steve Pestka, saying Amash's campaign had to dash to ensure they'd eke out a win.

Amash still bested Pestka by 9 percent in the November general election, but that was the least of Davis's arguments:

Amash doesnt yet have the statewide name recognition (and the reputation thats sure to follow) necessary to win in a statewide election. If hes still at the point where hes - as the incumbent - concerned about a Democrat with a pile of cash, hes not ready to be running for a seat in the Senate.
