The latest NBC News-Mason Dixon Poll shows North Carolina voters within the margin of error on who they will vote for for president. In the poll taken last week, 49% supported McCain, and 46% supported Obama.
The candidates are vying for the undecided voters. Obama will try to shore up support at a rally in Charlotte Monday afternoon. The McCain campaign has increased advertising to match Obama ad for ad, if not outpace, in battleground states like North Carolina.
