I'm not so sure. I think Obama made a BIG mistake when he went after the phone records of the AP. I think that will more than likely make a sea change in the media's covering of these scandals. The media was fine with Obama going after the GOP and conservatives, but will not abide by him going after THEM.
The media piled onto Clinton in '93, rallied behind him again for the '94 elections, piled onto him again in '95, rallied behind him again for the '96 elections, piled onto him again in '97, then rallied behind him (and Algore) in time for the '98 elections.
The media is following the same pattern with Obama, except they remained too much in love with him since 2008 to say anything bad against him until this year. Plus, if you say anything bad about Our Glorious Leader you are clearly a racist, so that has also stifled them somewhat until this year.
I fully expect the media to rally around Obama and the Democrats next year, and then start piling on again after the 2014 elections. They will then rally around the Democrats again before the 2016 elections.
