As the 1st Congressional District campaign goes down to the wire, the race has tightened into a near dead heat.

A survey released Sunday night by the Democratic-leaning Public Policy Polling showed that Republican Mark Sanford had 47 percent to 46 percent for Democrat Elizabeth Colbert Busch. That was well within the poll’s margin of error. The special election is Tuesday.

The result confirms earlier polls that forecast a tight race in the Republican-leaning district, which includes parts of Beaufort, Berkeley, Charleston, Colleton and Dorchester counties.

Both Sanford and Colbert Busch were joined on the campaign trail this weekend. On Saturday, the Tea Party Express threw its support behind Sanford during a stop in Summerville.

On Sunday, U.S. Rep. James Clyburn, D- S.C., campaigned with Colbert Busch.

As the voting begins tomorrow, here is what election officials say voters ought to know:

When, where do polls open?

Polls open from 7 a.m. to 7 p.m. Tuesday in the same polling places as used in the March 19 and April 2 voting.

Go to postandcourier.com/politics for a list of polling places in Berkeley, Charleston and Dorchester counties.

Those who vote at schools should realize that these schools will be in session Tuesday (unlike during last year’s general election). It might be a good idea to avoid showing up early in the morning or in mid-afternoon, when most students are arriving or heading home.

What should you bring?

The state’s new Voter ID law will be in effect Tuesday — as it was with this year’s primaries.

Voters with a state-issued photo ID, such as a driver’s license, another DOT-issued photo ID, a new voter registration card with a photo, a U.S. passport or a federal military ID, should bring it to the polls.

Registered voters still may cast a vote without such an ID if they either bring their photo ID by the county election office later or cite a “reasonable impediment” as to why they don’t have one.

Such an impediment can be most anything, including “any other obstacle you find reasonable.”

Election officials reported few voters cast provisional ballots in the primaries because of the new rules, State Election Commission spokesman Chris Whitmire said.

How can voters learn if they’re eligible?

The 1st Congressional District follows no logical geographic lines but instead includes parts of five counties. To check which district you’re in, go to scvotes.org, click on the “Voters” tab and “Check your registration.” Doing so will clarify your congressional district.
