According to RCP, we've got primaries in California, Iowa, Maine, Montana, Nevada, New Jersey, North Dakota, South Carolina, South Dakota, and Virginia. The news has been dominated by California's, Nevada's, and of course South Carolina's - but they're all important, so if you're a voter in that state, hie yourselves and any reliable Republican voters within reach to a polling station. You can let the Democrats in your life sleep in, particularly in New Jersey and Virginia.
Also: KEEP YOUR VIDEO CAMERAS HANDY, PARTICULARLY IF YOU LIVE IN SOUTH CAROLINA. Anti-reform opponents of Nikki Haley and Bill Connor may be now past the point where their shenanigans can shape public opinion in time for the actual primary election, but there's plenty of things that you can do to illicitly affect an election. Fortunately, sunlight is an excellent disinfectant - and, remember: as Mark Steyn notes here, Helen Thomas was taken down by a flipcam. There's a reason that both Instapundit and I keep harping on this...
