Yesterday, in my winning ways of our lying pols post, I pointed to Slate’s Farhad Manjoo asking Why isn’t Obama stretching the truth more often?

I don’t know if Obama took the advice, but today I read that he has gone negative:

In line with the expectations of most observers, the campaign has turned more negative since the conclusion of the Republican Convention. In the first week of advertising after the conventions, Obama aired a higher percentage of negative ads than did McCain. 56 percent of the McCain campaign ads were negative, while 77 percent of Obama’s ads were negative.

And, as Joe points out, he’s widened his lead over McCain to 4 points.

Thanks, Holly!
