Old data. I'd have agreed with you during the Marion Barry era. Anthony Williams has done a pretty good job. We are still dealing with legacy issues and have a disastrous school situation to address, but D.C. is headed in the right direction.
The next mayoralty election is important. Williams isn't running. The new guy will be a risk factor until he proves himself.
Similar to Atlanta. While not the worst, the multi-decade mayoral reigns of Andy Young, the corrupt Maynard Jackson, and the even more corrupt Bill Campbell, put the city in the running for a top-10 spot, for sure.
Shirley Franklin, the new mayor, seems pretty darn good, and certainly has things headed in a better direction, though like DC, there are plenty of legacy issues to be dealt with over time.
