Uh, no. The NBPP had a user-generated blog post on his campaign web site. Literally anybody who registered for the web site could have posted a blog endorsing him. There were over 1 million user-generated blogs on my.barackobama.com. Obama's campaign didn't put a NBPP endorsement on its web site. That's just a lie.
I'm all for criticism. People just shouldn't make shit up to make a point. It's so destructive to reasonable discourse. Just be honest. It makes conversation much more productive.
