Can Obama do anything about it? I have no idea. I'm not a politician. That's why I vote for politicians, so they can figure this shit out while I skin sabre tooth tigers in GS all day.
Is it unfair to blame Obama for what's going on? Probably, but that comes with the territory.
Republicans/Fox don't have to manufacture anything. There's plenty of shit to go around for everyone.
