These two maps, found at Daily Kos, show the progress that has been made toward establishing marriage equality in just the last year. At the end of 2013, there were 19 states where same-sex couples could legally marry (the states in red). Now there are 35 states where marriage equality is legal. That's 16 new states in 2014 alone.
This thing is really starting to snowball, and with a majority of Americans now favoring legal same-sex marriage (and the increasing likelihood of a favorable Supreme Court decision), it could be legal in all 50 states by the end of 2015 or middle of 2016. That will bring us another step closer to true equality under the law in this country, which is guaranteed by our Constitution.
