A joint polling effort in eight traditional battleground states shows that in all but one â??Barack Obamaâ??s home state of Illinois â?? the presidential race remains a nail-biter.
Eight Big Ten universities have partnered up to conduct presidential polling in Ohio, Michigan, Pennsylvania, Indiana, Wisconsin, Iowa, Illinois, and Minnesota. In each state, 600 registered voters were surveyed on the race between Obama and John McCain. The polls have a four percentage point margin of error.
