The current high-profile battle over union rights in Wisconsin is sort of the canary in the coalmine for union prospects all over the country, as the Koch brothers widen their anti-union efforts
to other states. There are many signs that Pennsylvania will be getting this movement soon, including some news reports
about their announced strategy.
I can tell that regional activists are gearing up because in the last 48 hours I've gotten not only a couple of email alerts but also a lengthy poll concerning my views on unions, response to various ways of explaining the issues, and leanings on some particular policy proposals (changing public worker pensions to 401k's, privatizing state liquor stores, and allowing non-union workers to work in unionized businesses). Pennsylvania has pretty deep union roots, so this is likely to be a pretty intense battle -- it's clear that the economy is being used as an excuse for pushing a larger corporate agenda in shifting the balance of power between large companies and their employees, and we need to be cautious about making long-term changes due to short-term worries.
