IBD/TIPP Tracking Poll Posted: Wednesday, October 15, 2008 Obama maintained a 3-point lead over McCain going into their third and final debate. Among the early trends in our tracking poll is an increase in undecideds among respondents 65 and older. There are now almost as many sitting on the fence in this group as there are among independents, where the race is tight. McCain could also be doing better among conservatives and married women. About IBD/TIPP: An analysis of Final Certified Results for the 2004 election showed IBD's polling partner, TIPP, was the most accurate pollster of the campaign season.
