Here's a wrap-up of the four major national tracking polls for today. With one new day of post-debate data within the three-day tracking polls, Barack Obama's lead is growing.
Gallup: Obama 50%, McCain 42%, with a ±2% margin of error. Yesterday, Obama was up 49%-44%. Rasmussen: Obama 50%, McCain 44%, with a ±2% margin of error, unchanged from yesterday. Hotline/Diageo: Obama 47%, McCain 42%, with a ±3.2% margin of error, compared to a 48%-43% Obama lead yesterday. Research 2000: Obama 50%, McCain 43%, with a ±3% margin of error. Yesterday, Obama was up 49%-43%. Adding these polls together and weighting them by sample sizes, Obama is ahead by a margin of 49.7%-42.9%, up from a lead yesterday of 49.3%-43.8%. These numbers entirely span the time since John McCain announced his quasi-suspension of his campaign to deal with the financial crisis, and they include one day of post-debate data. And it looks like that period of time has been very favorable for Barack Obama. Link to each poll here: http://tinyurl.com/5yqeah
