There was certainly significant movement in a libertarisn direction:
Ballot initiatives measure actual popularity of social movements, and the resounding victories last victories of ballot measures to approve the legalization of marijuana and to support gay marriage amount to a stunning shift in public opinion in favor of freedom.
Voters approved gay marriage in three states, Maine, Maryland and Washington, and defeated a ban on gay marriage in Minnesota. They approved legalizing the use of marijuana in two states, Washington and Colorado.
It was the first time that either issue had been approved in a state ballot referendum.
