Voters head to the polls thisSaturday in South Carolina for the first Republican primary in the South, and Donald Trump still holds a big lead in an average of recent polls. The closest candidate who conceivably could stop him is nearly 20 percentage points behind. South Carolina polls give Trump 37 percent of the vote and Sen. Ted Cruz, R-Texas, 18 percent. Trump’s support appears nearly unshakable.
