Public employees the weight around Dems' necks?

Again at Powerline:

[In San Francisco] a third of the city work force makes more than $100,000 each. The retired deputy police chief earned $516,118 in his last year, thanks to saved up vacation days, sick leave, overtime, etc. It is, of course, the last year's compensation that largely determines the size of the pension public employees get. 

The Democrats can't walk away from the public employee unions who negotiated these     arrangements because they are boholden to them. Moreover, Dems' hands-on complicity can't be denied.
