In this Oct. 2, 2012 photo, former Republican U.S. Rep. Tom Tancredo speaks out in favor supporting Amendment 64 to legalize marijuana in Colorado during a news conference at the Capitol in Denver. Tancredo, a suburban Denver Republican who briefly ran for president in 2008, launched a radio ad this week in which he compares marijuana prohibition to alcohol prohibition as a “failed government program” that, in this case, “steers Colorado money to criminals in Mexico.” (AP Photo/Ed Andrieski)
