South Carolina 'Shattering' Turn-Out Totals?

According to early-morning totals, looks like it could be on a pace to do that. Notably for Obama, this info comes from predominantly black precincts:

Several black precincts in Richland County, where Columbia is located, reported hitting 25 percent of all registered voters by midday, according to state party officials.
Lexington County, a predominantly Republican County next door and to the west, also is seeing spikes. In one Lexington black precinct, 80 people total voted in 2004; today, 95 had voted by noon. In another black precinct, 59 people voted in 2004; by noon today, 118 had showed up. In mixed precincts in Lexington, numbers were higher as well: one reported 149 voters as of noon today, compared to 176 in 2004. And, in one predominantly white precinct in Lexington County, twice as many people had voted as of 10:20 this morning, as in 2004.
