A reader in Chicago makes a good anti-mayor Rahm case:

Jonah,
Emanuel has advanced his career by ever-deepening his relationships with trade unions and public sector unions; the two biggest threats to the future prosperity of Chicago. Half of Chicago Public Schools 300,000 students will leave without a diploma (most of them black or Hispanic) and the economic engine tasked with paying the socials costs for this failure is sputtering on its way out of town where antiquated union rules won’t bankrupt them. Take a look at all the conventions that have decamped to Orlando or Las Vegas. I don’t expect Andy Stern’s buddy to correct any of these structural threats, but he may squeeze some more money out of the federal government until President Obama is shown the door. And the last thing this town needs is more of the back-room deal-making in which he specializes. We’ve had no lack of “executive decision-making” in this town. That’s how we wound up selling all of our parking meters for half their value to meet current obligations. No thanks.
On your Good Democrat/Bad Democrat spectrum he can be found at the far end of the bad side. I’m going to start packing my bags.
