Here is a quick look at voter registration statistics for North Carolina:

There are more than 2.6 million Democrats and 1.2 million unaffiliated registered voters in the state, all of whom are eligible to vote in the May 6 primary. So in total, more than 3.8 million people could potentially vote in the Democratic primary, which will allocate 115 pledged delegates.

According to the North Carolina Board of Elections' most recent (April 19) voter registration statistics, more than 1.18 million registered voters are black -- this includes all parties. The most recent chart that breaks down party registration by race (Jan. 2) shows that 96% of all black registered voters are either Democrats or unaffiliated. If we assume this percentage still applies four months later, blacks make up 30% of all eligible Democratic primary voters.

This clearly should help Obama, who has garnered an overwhelming majority of black votes throughout the primary process. Obama currently holds a 15.5-point lead in the RCP Average for North Carolina.
