No, at least not according to the rarely-liberal Pew Research’s study.
The nonpartisan report from the Pew Research Center’s Project for Excellence in Journalism found that it was Mitt Romney’s primary win in his home state of Michigan on Feb. 28 that convinced journalists he was certain to be the Republican standard-bearer; from then on, coverage of his candidacy grew considerably more positive.
But the most interesting nugget in the report, which is based on “analysis of the tone and volume of candidate coverage during the 2012 primary season from January 2-April 15 using human coding of 52 key news outlets and computer-assisted coding of more than 11,000 news outlets,” is that Barack Obama has been subjected to sustained negative coverage as Republicans have fought to challenge him:
Now, I’m going to go out on a limb and say that this isn’t proof that the press is “conservative”, per se. Rather, it’s always beneficial to lean your coverage toward the underdog and against the establishment. There’s a president and things kinda suck, so the media will be against him.
