CSPAN Video 30: Parry-Giles and Farnsworth Return to Discuss Presidential Campaign Ads

In this C-SPAN video clip, Professor Parry-Giles and Professor Farnsworth return to discuss presidential campaign advertisements.  This time around, both discuss Senator McCain's "attack ads" and whether or not they are efficient.  One of Senator Obama's advertisements is also shown, and Professor Farnsworth discusses the nature, substance, and impact of that ad; the professor is particularly critical.  Some interesting analysis.  Enjoy!
