The group claims to be nonpartisan, but is fairly liberal. So we shouldn't put a ton of stock in theeir findings. But it'll be interesting to see if the speech affected swing voters in other polls also.
Democracy Corps did dial testing and focus groups with 50 independent and weak partisan voters watching President Obama's speech last night and found "these swing voters reacted strongly to Obama's message."
Key findings: "Support for Obama's plan jumped 20 points, from 46% before the speech to 66% after. Importantly, Obama also achieved one of his principal goals of boosting the intensity of support. Prior to the speech, just 2% of these swing voters supported the plan strongly while 26% opposed it strongly; by the end of the evening those numbers were virtually reversed, with 28% supporting the plan strongly against just 8% strongly opposed."
