A poll from last week shows that Bob Casey's lead over Rick Santorum was about 11 points, and one from yesterday shows it at about 9. If Casey's lead is shrinking, perhaps it is because of the ads he is running.
You can listen to this radio ad that criticizes Santorum on immigration but then states that Casey supports the McCain bill. Umm…has anyone told Casey that the McCain bill was unpopular? Then there are the TV ads, which try to paint Casey as favoring fiscal responsibility, but then call for reducing the deficit in a way that only a moron would mistake as anything other than raising taxes. Hasn't anyone on the Casey campaign heard of the "bridge to nowhere"?
