As I've said before, today I'm live-tweeting the election as "SuperTuesday" on Twitter - www.twitter.com/supertuesday - and I'll be part of a team live-blogging returns and reaction tonight at Virtual Vantage Points.
If you're live-blogging or tweeting, let me know. We'll follow you.
If you're in a primary (or caucus) state today, don't forget to vote! And remember to thank a poll worker.
