Rep. Justin Amash (R-Mich.), frequently called "the next Ron Paul" and the only libertarian in Congress, has attacked Libertarian Party presidential nominee Gary Johnson on his Facebook page for Johnson's support of subsidies for the movie industry. Amash linked to a Politifact story from mid-July on Johnson's support of film credits while governor of New Mexico. Then let loose:

This appears to be the first time Amash has gone after Johnson publicly. Amash told me that although he enorsed Ron Paul in the primary, and will make no other endorsements, he will support the GOP nominee after the RNC convention.

Johnson's campaign said he was unavailable for comment on the Amash Facebook post but noted that Johnson has defended the policy in the past. In the Politifact story he stands up for his signing of the legislation saying that New Mexico has become a "second Hollywood". Politifact rated this as "half-true" saying that New Mexico is probably closer to third or fourth behind New York and Louisiana and that the film credits helped make it "player in the movie industry."
