North Carolina Democrats haven’t jumped the Barack Obama ship over his remarks about “bitter” voters clinging to the taboo subjects of religion and guns, according to a new poll. The one-day survey of 541 voters found Barrack Obama leads Senator  Hillary Clinton 51% to 36% ahead of the May 6 primary. The survey was conducted on April 14th, proceeding a very intense week of campaigning. The pollers said there was no significant change since the survey in March, and that because so much of the state’s Caucasian   vote is concentrated around colleges in the “Research Triangle”.
