Ditto on what JHB said.
Sandy, you have admitted in another post that you're getting a crash course in how the PTO works, so I hope this experience encourages you to be more involved in the future, *not* to write it off.
And, as JHB pointed out, not all political activity is off-limits--the determining factor is whether it's "substantial" activity. I doubt what happened at that last meeting would be deemed substantial in the grand scheme of all the PTO does. And, the person who talked about her husband working so hard on the bond issue was not campaigning for her husband as an individual, merely pointing out that her husband supported the bond issue and asking other like-minded individuals to help out. Uncomfortable and inappropriate, true--but the bottom line here is that the PTO President let the meeting get a little out of control.
Although DaveP disagrees with me, I stand by my statement that I think the school encouraging people to come in and vote is a good thing, as long as it was done properly.
We had a school bond referendum on our ballots earlier this week, and about a week before the vote, I got an e-mail from the school district reminding me that the vote was coming up, and explaining what the bond would be used for. I thought this was an excellent reminder, and appreciated the information--even though they didn't give me a donut with it.
