From the post:
The stereotype of the liberal atheist becomes untenable when it is conversely assumed that because there is a good chance atheists are leftists, there is similarly a good chance that liberals are atheists. In the US, theism continues to be the dominant position across the political spectrum. Fewer than 3% of those on the liberal side of the political spectrum describe themselves as atheists. Eight percent are agnostic, while an overwhelming 89% are theistic.
The short answer is yes–atheists tend to be a bit to the left, but most self-described liberals are still theists (because most people are theists). ::
