The document discusses how faith impacted the 2008 US presidential election. It found that while the structure of faith-based politics was similar to 2004, Democrats made gains among minority religious groups but only modest gains among white Christians. Religious affiliation is closely tied to factors like race and ethnicity. Religiosity, or levels of religious commitment, further divides groups and has been a key factor for white Christian voters in recent elections. However, the overall change from 2004 to 2008 was modest, influenced by strong partisanship within religious groups and faith-based get-out-the-vote efforts.
