S.C. goes to polls, why isn't all voting on Saturdays?

WASHINGTON – Perhaps half a million South Carolina Republicans are heading to the polls to vote for their party's nominee for president — on a Saturday.

"Our voters sure seem to like it," says South Carolina GOP Chairman Chad Connelly. "They don't rush in at 5 or 5:30 and have to wait in a big line. There's no question about it: We get a bigger turnout."
So why doesn't everyone vote on the weekend?
The answer lies in the 1845 law requiring all federal elections — first presidential, and later congressional — to be held on a Tuesday. That's because lawmakers were trying to find a day people could travel to the polls between Sunday (the sabbath) and Wednesday (market day) at a time when voters often had a half-day of travel to vote in the county seat.
"It's all about making election day as convenient as possible, but for the society of 1845," says Jacob Soboroff, director of Why Tuesday?, a group founded by former U.N. Ambassador Andrew Young to advocate reforms to boost voter turnout.
Many other democracies with higher turnout rates hold elections on weekends, and the 33 states that allow early voting have seen a spike in poll traffic the weekend before an election — especially in urban areas where African-American churches coordinate rides to centralized voting places, says Tova Wang, a fellow at the Demos Foundation, a liberal think tank.
But the impact of full weekend voting is "hard to predict unless you try it," she says.
