Jim Lindgren of the Volokh Conspiracy tallies up the negative comments about the other side in Obama's and Palin's speeches and discovers that the Democrat spent more time disparaging the opposition. Read the concise and entertaining analysis here.  He concludes:

If one compares Palin's speech to Obama's, it appears to me that they used similar amounts of sarcasm (not much), but Obama made considerably more extensive negative comments about McCain and Republican administrations than Palin did about Obama and Democrats. Palin's negative comments, however, were on balance funnier, better written, and more pointed than Obama's. Neither candidate's comments were entirely fair in every characterization of their opponents' positions.  [emphasis in original]

By continuing to spread false memes about the nature of Sarah Palin's speech as if they were true, the press marches forward in the most biased season of political reporting I've seen since at least 1998.
