RALEIGH, N.C. — The two North Carolina Democrats seeking the nomination for U.S. Senate on Monday turned their attention away from each other and toward the task of attracting aloof voters to the polls.

Elaine Marshall and Cal Cunningham capped their months of campaigning with trips to phone banks Monday. Marshall was making calls from her campaign headquarters in Raleigh, and Cunningham was capping a trip across the state with a final set of calls from Wilmington.

The vote on Tuesday will decide who challenges Republican Sen. Richard Burr in November, but voters appear uninterested in the results, with only 38,000 turning out in early balloting.

Marshall, the top vote-getter in the May primary, visited Wilson, Fayetteville and Raleigh on Monday, while Cunningham, who finished second in the six-person race, was in Charlotte, Winston-Salem and Raleigh.

The Senate race tops the ballot that will also settle three Republican primaries for Congress and a Democratic race for state Senate.

In the congressional races, Bernie Reeves and Bill Randall, both of Raleigh, will face off in the 13th Congressional District, with the winner facing Democratic Congressman Brad Miller in November. Also, Harold Johnson of Concord and Tim D'Annunzio of Raeford will compete for the right to face Democratic 8th District Congressman Larry Kissell.
