Voters in 38 states voted on 176 ballot measures on Election Day.
Washington and Colorado became the first states to legalize recreational use of marijuana.
In Massachusetts, ballots are still being tallied, but it appears voters have rejected a move to legalize physician-assisted suicide for the terminally ill.
"My late husband Sen. Edward Kennedy called quality, affordable health care for all the cause of his life," Victoria Kennedy, the widow of the late Sen. Ted Kennedy, D-Mass., wrote in a Cape Code op-ed.
"Question 2 turns his vision of health care for all on its head by asking us to endorse patient suicide -- not patient care -- as our public policy for dealing with pain and the financial burdens of care at the end of life," she said.
With about 93 percent of the votes counted, the measure is failing by 51 to 49.
