Did higher levels of campaign spending buy George W. Bush the presidency in 2000 and 2004? And will all the money being spent on this year’s election move voters too? That’s the conclusion of an intriguing new political science paper that estimates that between 1972 and 2004, 13.6 percent of voters “incorrectly” pulled the lever for Republicans in presidential elections, while 8.7 percent “incorrectly” voted Democratic. Study author Sean Richey (a Georgia State University Professor) found that money was a factor. Republicans spend more of it, and that money often buys convincing and/or misleading ads.
