We used all of these: Rasmussen Reports, ABC News/Washington Post, Investors Business Daily/TIPP, Gallup, Monmouth/SurveyUSA/Braun, CBS News, NBC News/Wall St. Journal, Washington Times: JZ Analytics, Politico/GWU/Battleground.
Yep, just the main national tracking polls. We email every one out so at the state level it might get overwhelming. And we can't really put too much into a filtering setup since it's a product that'll autodeadpool in 2 weeks :)
