Not every one, but I hear support for Obama on news message boards and chat rooms all the time. The common thread among what they say is that Romney is a liar and a fraud, and that him being President would be much like the Bush Administration.
Whenever a Republican shows up in these places, his attacks on Obama get about a dozen counter-responses, and woe to those who show up wanting him to release his college records.
What's your source, may I ask?
