For some time now, there has been a great deal of discussion over whether younger white evangelicals differed from older white evangelicals in their political attitudes and priorities. Now comes a fascinating and important pre-election survey suggesting that younger evangelicals are indeed somewhat more inclined to vote for Obama and to hold more moderate views on gay marriage -- though they are still, on the whole, pro-McCain. The survey, conducted for PBS's Religion and Ethics NewsWeekly by Greenberg Quinlan Rosner, found that overall, McCain led Obama by 71 percent to 23 percent among white evangelicals. McCain's lead was even larger, 73 percent to 22 percent, among white evangelicals over 30 years old. But among those under 30, McCain led by only 62 percent to 30 percent.
