Good news for Sen. John McCain’s campaign: cheap, but effective TV advertising options abound, according to a new report by Nielsen PreView.
Chief among these thrifty advertising alternatives – the auto-themed Speed Channel, which Republicans are 52% more likely to watch, compared with the average American.
In comparison, Republican voters are 48% more likely to watch FOX News and 33% more likely to watch Country Music Television. 
The takeaway: well-placed cable advertising can reach core Republican constituents at a more favorable CPM.
