Getting your Trinity Audio player ready...by DYLAN NOLAN***The race to replace South Carolina senator Lindsey Graham is consolidating around one main primary opponent, according to a new survey released by the Washington D.C.-based Big Data Poll. The new poll (.pdf) assessed support for Graham and his two top challengers – Paul Dans and Mark Lynch. According to the survey, Graham’s support slipped from 49.5% to 46.3% between June and September. While that shift is narrower than the poll’s ±3.5% margin of error, there were statistically significant shifts in who anti-Graham voters are backing. The number of undecided voters decreased by roughly six percent to 20% of survey participants.
