TRIPLE-UPDATE: Okay, so the anti-tax group is apparently fairly random in its targeting. The D16 version targets all three Delegates (Frick, Lee, Kelly). Meanwhile, a D39 reader reports on more conflicting information about the mailing:
D39 READER: Just wanted to give you a quick update on District 39. I received a mailer yesterday as well. It only targeted Delegates Reznik and Barkley, and not Delegate Robinson. Del. Barkley and Reznik both voted against the tax plan, and Del. Robinson voted for it. So, it goes counter to your thinking on the D18 mailer, where Del. Gutierrez was not targeted. So, frankly, I have no idea what their logic is. Also, our mailer did not have the home phone numbers of the officials.
