My dad was just flipping through the channels and got to CNN, where Anderson Cooper was hosting a special called "What is a Christian: Where do You Fit In?", a collection of reports on different Christian denominations in the U.S. It's a pretty interesting look at the power of Christianity in America, especially the rise in Evangelicalism. The special also goes into the influence of all this in politics and foreign policy and how this relates to the overwhelming belief in America that the "End Times" are coming soon...
Of course, as it was shown on CNN, take it with a grain of salt.
The whole report is on YouTube in a series of parts:
"What is a Christian: Where do You Fit In?"

Ken Jacobson of ADL says: "We kind of feel like we'll worry about it when it (End of Days) comes. Uhh, meanwhile, in a world where Israel is under siege, having so many millions of Evangelical Americans support Israel is of immense benefit"
