Republican insiders tell National Review Online that Representative Justin Amash of Michigan is privately considering a Senate bid, should incumbent Democrat Carl Levin retire. 
  
 “People are asking him to look at it, and he hasn’t closed the door,” says a Republican operative familiar with Michigan politics. “If Levin steps down, I think he’s going to run.” 
  
 Several libertarian activists say the 32-year-old congressman is intrigued by the idea. He recently huddled with his friends and allies to express his interest. 
  
 But no decision is imminent. Amash is waiting to see whether Levin, who has less than $250,000 in his campaign account, will formally announce his plans. Levin, the chairman of the Armed Services committee, was first elected in 1978. 
  
 Amash, a vocal critic of Speaker John Boehner and a popular presence on Twitter, is known as the libertarian bad boy of the House GOP. He was famously kicked off of the budget committee last year for his quarrels with the leadership. 
  
 Amash also voted against Boehner during the speaker election in January. Instead of backing the Ohio Republican, he cast his vote for Raul Labrador, an Idaho conservative and a fellow Republican sophomore. 
  
 Amash’s consideration is alarming to Michigan Republicans, who are hoping to back a more established candidate, especially if Levin retires and the seat opens. 
  
 Amash, as a youthful conservative with a national following, would be a force in a primary. Many Ron Paul supporters see him as a libertarian leader for a new generation. ||||| Obama praises Levin: 'No one has worked harder' to bring jobs

Democrats will have another Senate seat to contest in the 2014 elections: Carl Levin said today he won't seek re-election, reports the Detroit News. The 78-year-old has been in the Senate since 1979 and currently serves as chair of the powerful Armed Services Committee. "I can best serve my state and my nation by concentrating in the next two years on the challenging issues before us," he wrote in a statement. "In other words, by doing my job without the distraction of campaigning for re-election.” Michigan seats are generally safe territory for Democrats, notes the Detroit Free Press, which says Levin "has been a force for progressivism in the Senate." But the National Review previously reported that an intriguing GOP candidate, congressman Justin Amash, might be interested in running if Levin retired. The conservative Amash, 32, has a libertarian streak and has quarreled publicly with GOP leaders. He even voted against John Boehner's re-election as speaker. "Many Ron Paul supporters see him as a libertarian leader for a new generation," says the NRO piece.
