Answer to why Bloomberg is spending so much

From the NY Times:

With five weeks remaining until Election Day, little seems uncertain in the contest between the colossally advantaged incumbent, Mr. Bloomberg, and his lesser-known rival, William C. Thompson Jr.

But interviews with both campaigns and dozens of voters reveal that anger over a single issue still simmers, seemingly immune to a flood of television commercials and glossy brochures. That bedevils Bloomberg advisers and gives hope to his underfunded challenger.

Disenchantment over the change in the law helped topple four veteran City Council members this fall, the greatest repudiation of incumbents in a generation, and has catapulted two local lawmakers who opposed the measure into citywide office.

Mr. Thompson is building his entire campaign around the topic, adopting the slogan “Eight Is Enough,” accusing the mayor of breaking his word and preparing commercials that portray him as a power-hungry mogul who plays by his own rules.

The mayor’s political advisers privately acknowledge the public anger, but since they cannot reverse Mr. Bloomberg’s actions, they are looking for ways to deflect attention from it.
