Yes, it's a single-issue election

Mr. Obama was exactly right in Cleveland when he said economic growth “is the defining issue of our time,” that his and his opponents’ views on growth are fundamentally different and “this election is your chance to break that stalemate.” This he gets. Only the most obtuse “pragmatists” persist in believing the solution lies in a mystical center somehow combining elements from this ideological oil and water.

Put differently, this is a substance election. It’s not about whether one “likes” Barack Obama or can’t warm to Mitt Romney. Voters have to pick two competing growth models, which means paying attention to what the candidates are saying about economic growth. …

Mr. Romney has been giving fine speeches on “the liberating power of the free enterprise system.” One hopes the Romney camp doesn’t think everyone knows what that means. These are difficult and confusing economic times, and Team Romney should not underestimate the appeal of Mr. Obama’s confused economic ideas if drilled daily into the electorate’s soft clay.
