The poll showed that support for Trump would stand at 46 percent to Clinton’s 43 percent in a general-election contest between the two, suggesting that a Trump nomination augurs a competitive race in the deep-red state.
By contrast, if the Republican nomination goes to Sen. Ted Cruz (R-TX), the poll shows him leading Clinton by 11 percentage points at 51 percent to 40 percent. Ohio Gov. John Kasich (R) performs even better among Mississippi voters, who prefer him to Clinton by 15 percentage points, 52 percent to 37 percent.
The Mason-Dixon survey was carried out form March 28-30 using live telephone interviews. Pollsters surveyed 625 registered voters, with a margin of error of 4 percentage points.
