Remember how we explained yesterday that the mayor's campaign against a new water/sewer board was picking up cash? And that you should expect labor unions to add to that tally soon?

In the scant hours since, the Stop the Bull Run Takeover campaign has reported a sizable $10,000 donation from the American Federation of State, County and Municipal Employees (AFSCME) Local 189, which represents hundreds of Portland Water Bureau staffers.

The donation, as I say, was expected. Joe Baessler, statewide political director for AFSCME, previously told the Mercury he was simply waiting for word on where to send a check.

The $10,000 is big, but it's still small potatoes compared to the multiple checks of equal or larger size cut by industrial ratepayers and property management groups for the Portland Public Water District campaign, which is proposing a new seven-member board to oversee the water bureau and Bureau of Environmental Services.
