Fox News: We're All Democrats When Scandal Breaks
In 2006 Fox News misidentified Mark Foley as a Democrat when the GOP congressman resigned after sending sexually explicit emails to teenage males. Clearly, network producers couldn't imagine a Republican doing anything scandalous and assumed Foley must be a Democrat. An honest mistake, right? (Hey, I'm trying not to be cynical.)
Well it's a "mistake" Fox News has made again: Wednesday, while broadcasting the news conference of Mark Sanford admitting to cheating on his wife, Fox ran a Chyron identifying the weepy South Carolina governor as... you guessed it, a Democrat. Oops!
