In pulling this off, Obama has two very substantial problems.

First, Mitt Romney will have an opportunity to define himself for the electorate, funded by hundreds of millions of dollars worth of television ads. And he has a compelling story to tell: family man and father of five, started his own company that invested in a lot of visible businesses, saved the Salt Lake City Olympics, and worked with Democrats in Massachusetts of all places. It is going to be easier said than done to stick either the Barry Goldwater or the J.P. Morgan label on him.

Second, and more importantly, this is not what swing voters want to talk about. Think of the campaign in terms of consumer economics: Customers want Walmart and Target to stock their shelves with certain items at certain prices, and the purchasing power of their dollars forces the two firms to comply. Well, our parties are like Walmart and Target, the voters are their customers, and the campaigns are like the marketplace. In the competition for votes, the two parties invariably end up talking about what the country, and in particular the swing vote, wants to talk about.

I’ll bet you dollars to donuts that the average swing voter does not want to talk about the “war on women,” the Buffett rule, or whatever else Team Obama is going to throw out there in the weeks and months to come.
