Obama 47, McCain 46, Barr 3

The presidential race in North Carolina is too close to call.

A new poll by the conservative Civitas Institute shows Democrat Barack Obama with 47 percent, Republican John McCain with 46 percent and Libertarian Bob Barr with three percent.

Five percent were undecided.

"All three races are too close to call and are inside the margin of error of our polling," said executive director Francis De Luca. "With very few days remaining until the election, two big factors will decide the outcome of all three races — who votes and which way the remaining undecided voters break."

Polls taken in the last month generally have generally showed Obama ahead by one to seven points, though McCain has been ahead in two recent polls and the two were tied in another. 

The survey of 600 likely voters was taken on Oct. 27-29 by Tel Opinion Research of Alexandria, Va. The margin of error is plus or minus 4.2 percentage points.
