I can explain this.
You may think that this looks like media bias —
Crooks and Liars » Romney Fundraising Scandal Ignored By Liberal Media – Clinton Gets Hammered Over Hsu: In recent days, NBC, CNN, and Fox News have all aired reports or discussed the case of Norman Hsu, who The Wall Street Journal suggested may have funneled illegal campaign contributions to Sen. Hillary Clinton. However, when Mitt Romney’s national finance committee co-chairman Alan Fabian was charged with mail fraud, money laundering, bankruptcy fraud, perjury and obstruction of justice, the three networks did not report or discuss it during programs available in the Nexis database.
It looks like the media protect Republicans and go after Democrats, right? Well, that may be true of Fox News and the Wall Street Journal, but I have a different theory as to why the rest of the media falls into this pattern.
You see, it's not news when Republican officials are involved in sleazy financial deals. It is news when it happens to Democrats. After all, it happens to Republicans all the time and only happens to Democrats occasionally — despite the vast disparity in prosecutorial resources devoted to trying to find dirt on Democratic office-holders as opposed to that devoted investigating Republicans.
(And don't even get me started on the frequency of GOP sex scandals.)
