Endorsing Initiatives

A fellow PTA member is gathering signatures for Initiative 594 which would increase background checks on gun sales.  She has requested that I set out the signature sheet at our next general PTA meeting.  She said the PTA was in support of this initiative.  Although I might be personally in favor of this initiative, I'm reluctant to bring anything political into our meeting.  However, if it is done unobtrusively it might be ok to have it at the meeting?
