Two new polls show tight race in N.C.

Two new polls show a tight presidential race in North Carolina.

A CNN/Time poll released this afternoon shows Republican John McCain leading Democrat Barack Obama 48 percent to 47 percent among registered N.C. voters. That's well with within the 3.5-point margin of error.

A survey of registered voters by the Raleigh-based Civitas Institute found McCain ahead 43 percent to 42 percent. Libertarian Bob Barr got 2 percent. When poll-takers asked undecided voters who they're leaning to, McCain's lead moved to 47 percent to 44 percent, with 8 percent undecided.

The margin of error in the Civitas poll is 4.2 percentage points.
