Public Policy Polling, a Democratic polling firm, has the NC race for president a dead heat based on its weekend polling.

It’s now 49 Obama, 48 McCain, 1 Barr.

McCain is gaining, writes pollster Tom Jensen, and it could boil down to weather, if Obama hopes to win. From Jensen’s blog:

The deciding factor for President in North Carolina could be the weather on November 4th. Barack Obama is banking a huge lead among early voters, 63-36, who account for about a third of the likely electorate. But John McCain is up 53-42 with folks who plan to vote between now and election day. A rainy day could be to Obama’s considerable benefit.
