Actually, Mr. President, money doesn’t decide elections

The most alarmed coverage concerns the skyrocketing spending of independent groups. It is true that Republicans have an edge when it comes to outside expenditures. This year, for example, the United States Chamber of Commerce is spending $22 million for Republicans, while the Service Employees International Union is spending about $14 million for Democrats.

But independent spending is about only a tenth of spending by candidates and parties. Democrats have a healthy fear of Karl Rove, born out of experience, but there is no way the $13 million he influences through the group American Crossroads is going to reshape an election in which the two parties are spending something like $1.4 billion collectively…

In the end, however, money is a talisman. It makes people feel good because they think it has magical properties. It probably helps in local legislative races where name recognition is low. It probably helps challengers get established. But these days, federal races are oversaturated. Every federal candidate in a close race has plenty of money and the marginal utility of each new dollar is zero.
