A couple of article have come to my attention in recent days, both relating to religious progressives (mainly in the political and economic sense of that term).
First, Jack Jenkins wrote an article for Think Progress suggesting that progressive religious people will soon outnumber conservatives. Second, Robby Jones wrote in The Washington Post that progressive religion has more appeal with young people. The Huffington Post also has an article about this.
All of this is the result of a survey that suggests roughly one in five Americans self-identifies as a religious progressive. A press release from the Religion News Service summarizes the findings. A pdf with the report itself is also available online.
Most of the reporting focuses on progressives with respect to politics and the economy, rather than theological progressives. But as Tony Jones notes, the report includes the latter as well.
