He didn't get the spending reduced and a transparent plan in place to deal with the debt. The economy was heading in a good direction. Unemployment looked great. We weren't funding any major military conflicts.
Take that window to reallocate spending to pay off some of the debt! It's an area where Chris and I agree politically: Pay down the debt when the economy is growing. Be transparent and visible about what you're doing. Keep tax rates in place and let everyone know the plan.
None of this happened.
