This poll was conducted by Research 2000, and they were very accurate in 2000.. among the best. I think it's close to being accurate..
Mason-Dixon had Bush by 7 in a mid-May poll., Mason-Dixon was also very accurate in 2000.
Two of the best polling services from 2000, have similar results, I think we need to accept them as fact, unless you want to keep your head in the clouds and only accept good news and ignore bad.
Research 2000, 6/13-6/16, Bush 47-42.
Mason-Dixon, 5/14-5/17, Bush 48-41.
I would put Bush's North Carolina lead at 6.
Please cite where I have kept my "head in the clouds" and only accepted good news while ignoring bad. I think most people who read my posts on a regular basis would vouch for my objectivity in interpreting poll results, and say that I probably lean a bit to the more cautious side.
