If two teachers send a note in support of a ballot measure en masse to the school e-mail addresses of thousands of other teachers, is that a no-no?

That's just one piece of the issue of the week being peddled to reporters covering the union dues initiative Proposition 75.

In a nutshell: a pair of teachers, in coordination with the "Yes on 75" campaign, sent an e-mail in support of the initiative to some 90,000 teachers on Wednesday. The note went to the official school e-mail addresses of the teachers, and apparently discussed the political spending habits of the California Teachers Association (which is sinking big bucks into the fight against Prop 75), as well as urging a yes vote on the initiative.

Today, the CTA alleged that the mass e-mailing of the political message to school e-mail addresses was illegal under the state Education Code. CTA attorneys say they'll ask local district attorneys to investigate and possibly prosecute.

In a conference call with reporters on Wednesday, the "Yes on 75" campaign said they basically tasked some interns to dig around online and track down the e-mail addresses. Meantime, in a conference call today, CTA officials said they responded with their own note to the teachers-- but sent it instead to home e-mail addresses.
