The DUers regard Snopes as the next thing to Fox News in the Pantheon of Evil, but I have always found them to be rather down the middle, neither particularly left nor right.
The main purpose of their item was to examine what was or wasn't factual in a widely-circulated email, and it doesn't do a bad job. Sure, they probably could have done better than relying on a Wikipedia article for part of it, and the writer appears to not fully understand the significance of BHO's very large number of "Present" or "Abstain" votes on controversial issues like guns to issue advocates, but it seems rather middlish to me.
