Washington Senate today becomes 14th legislative house to pass bill.

"Earlier this month, Massachusetts voters got a taste of what it feels like to count in the presidential race. And how refreshing it was! In previous campaigns, the state's presidential primaries came too late to affect the outcome of the major parties' nomination battles, and the inclination to vote Democratic in November meant that its electoral votes were rarely in play. This year was different.

Confronted on Feb. 5 with competitive Democratic and Republican races — and the possibility that the outcome in Massachusetts might influence the results for once — the electorate turned out in record numbers. Voters in every state deserve the same opportunity in all presidential elections."
