We've seen this before, but the issues have really come to a head in this Connecticut town election.

PTO Council sponsoring a candidate's forum (perfectly OK, by the way), but all Republican candidates boycotting it because the PTO president had a recent letter to the editor in favor of the Democrats.  Her biggest mistake -- she signed that letter with her PTO title included. 

The real trick: will Republican parents now hesitate to join the local PTO?  Hope not, but I imagine they're facing a real involvement challenge in that town right now.  What a good lesson in why we have to be so careful about mixing politics and PTO work.  The two can often be at odds, whether it's an issue campaign ("support the tax levy for our schools") or a personal campaign like this one.
