Despite $2.6 million raised by groups opposing the measure, its proponents were able to raise more money and garner far more votes, with support for the amendment winning by a more than two-to-one margin.

“When you pass a bill by such a significant majority,” said Toni Broaddus, acting national director of political affairs and advocacy at Compassion & Choices, “it just demonstrates the non-partisan nature of this issue and the widespread support.”
