Well, just for the sake of discussion, I'll raise the following counterpoints.
Regarding baseball, a new stadium was one of the up-front conditions for placing the team in DC. Although the wisdom of taking the deal is certainly debateable, MLB didn't misrepresent the situation or hold a gun to the city council. The mayor was definitely a backer but the city council made the decision.
As for the schools, they are under the jurisdiction of the board of education, not the mayor. The mayor's bid to gain control of the school system was defeated in the city council. I agree that the schools are jacked, it's just hard to lay that at his feet.
As to the 45% illiteracy rate, is that right? Dayum.
