Not only is the Sun-Times, as Tom Roeser puts it, the Democratic newspaper of record, I'll take it a step further. It's like a corporate PR firm hired to promote the party.
First it gives Rahm Emanuel two pages to excerpt his book outlining his new contract for America. Then, it gives Barack Obama wall-to-wall stenographic coverage of his trip to Africa, complete with a separate web page and fawning video interviews of other Democrats talking about the trip.
Meanwhile, back on Planet Earth, the Democrats in Illinois are engulfed in robust corruption investigations of the Mayor and Governor. The Sun-Times is most egregiously negligent when it comes to Emanuel. He has been implicated in the city of Chicago investigations as receiving illegal political help, yet instead of intense questions from the paper, he gets intense promotion.
