The third party candidates' tax plans were not studied by mainstream media outlets and the Tax Policy Center. Chuck Baldwin supports replacing the income tax with a 10% across-the-board tariff on imported goods.  Bob Barr supports replacing the income tax with a consumption tax (the FairTax ). The details of his exact plan are not known but consumption taxes tend to be regressive unless accompanied by a negative income tax for the poor to offset necessary expenditures.  Cynthia McKinney supports sharply progressive taxation , with higher taxes for the rich and a tax cut for the middle class. 
In a media-saturated environment in which news, opinions, and entertainment surround us all day on our television sets, computers, and cell phones, the television commercial remains the one area where presidential candidates have complete control over their images. Television commercials use all the tools of fiction filmmaking, including script, visuals, editing, and performance, to distill a candidate's major campaign themes into a few powerful images. Ads elicit emotional reactions, inspiring support for a candidate or raising doubts about his opponent. While commercials reflect the styles and techniques of the times in which they were made, the fundamental strategies and messages have tended to remain the same over the years.
