Substance? I Like Substance.

This morning I found this article by Paul Krugman about how much (or little) substance there is currently in the primary campaigns.

The way I see it, the substance on the Democratic side has been spurred on by John Edwards need to find a foothold against Obama and Clinton.

On the Republican side there isn't quite as established a hierarchy. Sure, Rudy Giuliani is the front runner, but some of his more liberal stances make him vulnerable. Without any Clinton or Obama like front runners there is little incentive for a 2nd tier candidate to put forward the substance of their policies since it would just be dissected by the rest of the field. I hope we'll see more substance from the republicans as the primaries start to rank the pecking order of candidates and it becomes more advantageous for somebody needing a boost in the polls to push for more substance in the campaigns.
