Dave Weigel comments:

Voters in Maryland [where Murray lives], Washington, Maine, and Minnesota are all voting on gay marriage measures. In the first three states they’re voting on legalization; in Minnesota, they’re voting on a ban. Whichever state legalizes gay marriage by popular vote today will be the first to do so, breaking an eight-year streak. By 10 p.m. or so, it should be clear whether or not Richard Tisei has won a House seat in eastern Massachusetts. If he does it, he’ll be the first-ever elected gay Republican congressman. And later in the evening — if it’s that early — we’ll know whether Rep. Tammy Baldwin has become the first openly gay senator. The potential for a lot of heartbreak here, but for anyone who remembers Prop 8 in 2008, passing hours after the state’s liberals celebrated an Obama win, it’s one hell of a reversal.
