Forget yellow. At least for tomorrow. Because in all of the most important states, there will be Presidential Primary Action! Go vote! Your vote tomorrow will mean more than the one in November. I guarantee it.
You need to be registered as either a Democrat or Republican to vote. If you aren't registered, no worries! They'll let you register on the spot (at least in Utah anyway). And if you're like me and prefer to be Independent, no worries again! You can go back to your indie status right after you vote.
Now that's what I call a win-win. Go Hilary, Barry, Ron, John and Mit! (Not necessarily in that order, of course).
