Using a Facebook app and a poll on CNN.com (and on Thursday, text messaging and phone-ins) the network is attempting to conduct a national poll reaching as many citizens as possible.
The CNN National Report Card: Second 100 Days is a TV show happening from 8pm till 10pm this Thursday, but it's also another attempt by CNN to leverage user interaction online. In addition to the Facebook poll, they're soliciting videos on iReport, CNN's user generated reporting site, in which viewers explain the reasons behind the grades they gave. The best videos will be aired on CNN.
It's hardly the first time CNN has leveraged social media in its initiatives. Back in 2007 the network partnered with YouTube to host both Democratic and Republican debates, while iReport launched in 2008. More recently, CNN has worked with Facebook to live stream events (like Obama's Inauguration) with realtime Facebook chat.
