Yes, according to the Washington Times.

Other potential 2016 GOP contenders, including Gov. Scott Walker of Wisconsin, Gov. Bobby Jindal of Louisiana, former Texas Gov. Rick Perry and former Arkansas Gov. Mike Huckabee have all previously signed the pledge in some capacity.

I will withhold judgment on them until I hear they have signed the same pledge for 2016. If so, they won't get my vote. I have worked personally with Norquist at CPAC. He is an arrogant a$$hole who is bilking people to feather his own nest.
