The next round of nominating contests occurs today, as Republicans in South Carolina and Democrats and Republicans in Nevada go to the polls/caucuses. The South Carolina primary starts things off, with polls opening at 7:00 am ET and closing at 7:00 pm ET. The Nevada Democratic caucuses, meanwhile, take place at 2:30 pm ET (sites open at 2:00 pm), and the state party expects to have results by 5:00 pm ET. Theses caucuses operate just like the Iowa Dem ones did — caucus-goers can make a second choice if their original pick doesn’t receive a minimum threshold of support. And the GOP caucuses in the state follow the Iowa GOP model — they’re more like a straw poll and there is no second choice. They begin at noon ET, and results should start coming in at 1:30 pm ET.
