Steven Hayward of Power Line posts a couple of charts pollster Bill McInturff gleaned from ten+ years of NBC News polling. The first looks at percentages of Democrats calling themselves either "very liberal" or "liberal."
The second chart looks at the percentage of persons in the three major political groups - Republicans, Independents, and Democrats - who are not affiliated with a church.
Your perception that Democrats have become both more very liberal and less religious over the last decade is indeed correct. Hayward promises more interesting insights to come from this longitudinal look at social trends.
