West Michigan Congressman Justin Amash will not run for the US Senate next year after all.

The National Journal says Amash "established himself as the leading libertarian in the House" and, quoting unnamed sources, says that Amash decided within the past two days that running for the Senate may put his clout at risk.

Amash confirmed the National Journal in a tweet.

Former Michigan Secretary of State Terri Lynn Land is the only announced Republican running next year for the Senate seat held currently by the retiring Carl Levin.
