Anyone who follows politics knows that the mainstream media has two sets of rules: one set for conservatives and another set for liberals. Conservatives spend most of their time correcting smears and trying to explain to the public what they really believe. Liberals, on the other hand, can count on the press to hide their unpopular beliefs and put the best spin possible on everything they do. This is why you often hear Republicans say, "Imagine what they'd say if a Democrat had said that," while you almost never hear Democrats say, "Imagine what they'd say if a Republican had said that."
Those two separate sets of rules shape how politicians behave, how they're perceived, and the issues that they spend most of their time talking about. In Barack Obama's case, the media would be focusing on an entirely different set of issues if he were a Republican.
1) This guy is way too stupid to be President of the United States! Poor Dan Quayle was forever branded as stupid for misspelling the word potato. It's not often noted, however, that the card that he was given by the school had misspelled the word. Then there's Obama, the man who stammers without a teleprompter, the guy who won't release his college records. How does Quayle's gaffe compare to Obama thinking there are 57 states? Duhr! How about Obama walking into a window at the White House? Duhr, duhr! What about signing a guest book 2008 in 2011? Duhr, duhr, duhr! Obama's stupidity would be a staple of late night talk show jokes if he were a Republican.
