Major state election races come to a head in South Carolina on Tuesday as voters must settle runoff elections for Lt. Governor and Superintendent of Schools. Republican voters have both races to decide while Democrats only have a runoff vote for the Superintendent of Schools.

Clearly, the focus of the two-week runoff campaign has been the up and down battle for the Republican race for Lt. Governor between Henry McMaster and Mike Campbell.

McMaster, a former state attorney general, finished first in the June 10 primary with 43.6 percent of the votes. Campbell, the son of former South Carolina Gov. Carroll Campbell, came in third in the primary with nearly 24 percent of the votes. He advanced to the runoff when second-place finisher Pat McKinney decided to drop out of the race two days after the primary. The winner will face Democrat Bakari Sellers in November.

McMaster and Campbell brought out the big national guns over the weekend. Former U.S. Senator and GOP Presidential candidate Rick Santorum rallied in support of McMaster. Meanwhile, Santorum’s GOP Presidential opponent — former Governor of Arkansas Mike Huckabee — came to South Carolina for Campbell.

The race for the GOP spot for Superintendent of Schools has been surprisingly bitter and contentious.

The June 10 primary results were tight between Sally Atwater of Charleston and Molly Spearman of Saluda, with Spearman leading narrowly. Both received about 22 percent of votes, beating six other candidates.

Then, things got heated.

In the last two weeks of campaigning, Atwater, 63, has been accused of being “clueless” and Spearman, 60, has been accused of being a closet Democrat.

Only 16 percent of the state’s 2.8 million voters went to the polls in the original June 10 primary.

Voters who participated in the June 10 primary must vote in the runoff of the same party that they cast a ballot for in the primary. Voters who did not take part in the primary can vote in either party’s runoff on Tuesday.
