I agree. Work with your local groups, where you are. If there is not one, create one. And learn well the lesson that you shouldn't celebrate the victory before the votes are counted. You have to do the grass roots stuff, not the preaching to the choir stuff to win.
And remember well too, all of this was settled until out of state money came in and put it on the ballot. Funny, had it been an off-year election, without some charismatic figure running, I bet the results would have been different as the huge Hispanic and AA vote would not have been in play.
