The speeches are getting much tougher tonight at the Democratic convention, though so far the cable networks haven’t been showing all of them.

Bob Casey actually introduced a pretty good line. After pointing out that John McCain voted with George W. Bush over 90% of the time, he said that McCain shouldn’t be referred to a “maverick,” but instead should be referred to as the “sidekick.” Frankly, if this was written by the Obama campaign, they probably should have had a better speaker deliver it, but at least Casey did a decent job with it.
