You can see the comparisons between the two campaigns below in terms of dollars raised, spent, and cash-on-hand totals, as well as debts... It looks like Nussle has significant debt to pay off compared to Culver. This is clearly becoming quite the expensive gubernatorial race, if not the most expensive in Iowa history (which it was bound to be anyway judging from the political climate). I haven't had time to look over the reports in too much detail, but I'm sure we'll be hearing more about them soon.
