If you voted in the 2012 presidential election, your vote was one among more than 235 million. You were part of the process, but a decidedly small one.

If you vote in today’s congressional primaries, though, you could be one among only several thousand who participate. Your vote could make a big difference.

Votes in this unusual June primary are further magnified in the GOP primary for the 13th Congressional District because 17 candidates are on the ballot. There’s no telling how the vote will splinter. Victory depends entirely on getting out the vote.

Rowan voters in the district should pay close attention, since three local people are running —  Kathy Feather, Jason Walser and Harry Warren.

With a big chunk of Guilford County in the district, all of Davie and Davidson and most of Iredell, Rowan would have to have an extraordinary turnout for one of our candidates to prevail. The candidates would also need strong support in other parts of the district. Anything can happen.

On the Democratic side of the 13th district race, five people are running — normally a big field, but dwarfed by the Republican competition.

The 13th District includes Salisbury, part of Spencer and nearly all of the county that’s north of Mooresville Road.

More of Rowan lies in the 8th District, which has an easier slate to follow. It’s a two-man race for the GOP nod — Richard Hudson vs. Tim D-Annunzio — and there’s no Democratic primary.

The whole state is voting in the race for one seat on the N.C. Supreme Court, an important, nonpartisan contest.

Polls will be open from 6:30 a.m. to 7:30 p.m. Vote.
