In a recent discussion at the Conservative Political Action Conference, also known as CPAC, Texas Senator Ted Cruz revealed an unexpected stance on marijuana.

Cruz told Fox News host Sean Hannity that he endorsed marijuana federalism, and feels that the decision whether or not to allow the use of marijuana among residents should be up to the states giving the example of the recent legalization in Colorado.

Cruz said that, while he may not necessarily agree with states decisions on legalization, marijuana deregulation is a great embodiment of “the laboratories of democracy” described by Supreme Court Justice Louis Brandeis.

These comments are wildly inconsistent with Cruz’s past criticism of the Obama administration for failing to interfere with legalization in the states of Colorado and Washington.

Just a little over a year ago, Senator Cruz spoke at a Texas Public Policy Foundation Conference in Austin, Texas where he argued that the Justice Department should be firmly enforcing the federal ban of marijuana in those two states.

It remains unclear if Cruz has been swayed or is simply changing his tune to suit a particular campaign platform, and what this will mean for his 2016 supporters.
