The sound of Democrats' heads exploding

This sounds like quite the quandry for Philadelphia's liberals.

This city's hoped-for bragging rights as home of America's tallest environmentally friendly building could go down the toilet.

In a city where organized labor is a force to be reckoned with, the plumbers union has been raising a stink about a developer's plans to install 116 waterless, no-flush urinals in what will be Philadelphia's biggest skyscraper.

Developer Liberty Property Trust says the urinals would save 1.6 million gallons of water a year at the 57-story Comcast Center, expected to open next year.

But the union put out the word it doesn't like the idea of waterless urinals fewer pipes mean less work. [sic]

So, on the one hand, you've got people who want to build a Gaia-friendly skyscraper. Sounds laudable. But on the other hand, you've got union members--a big Dem voting block--who want to feather their nest. What's a lefty to do?
