When it comes to analyzing the news media, what kinds of stories or details are left out are more important than those included. For example, on your typical leftist-leaning paper, you'll rarely find corruption details against Democrats in office, and if you do, the fact that this representative is Democrat will not be mentioned except maybe as an aside in the last paragraph.
Another example: the left is making a big deal of Mitt Romney's income and large donations to his church. What's the big deal? That the guy lives his religion and pays his tithing? That the guy gives to charity unlike most elected Democrat officials? That he doesn't make as much money as the Clintons do and it's somehow OK for them to be multi-millionaires but not him? That he pays all his taxes? Are they going to do the same kind of article on Harry Reid because he's
also a Mormon or keep ignoring it because he's a Democrat unlike Romney?
Partisanship causes blindness on both sides. There are certainly plenty of problems on both sides of the aisle. You've got to read both sides anymore to get a good idea of what's really going on, because both sides leave stuff out.
The media does count on its followers being gullible enough
to not think for themselves. It is your duty to be a
well-informed voter, not a brainwashed and partisan voter. Food for your thought! To back me up, here is a FoxNews editorial on the subject of the damage wrought by under-informed voters.
