Can bond referendum propaganda signs be placed on public propert

Middle Township - Can bond referendum propaganda signs be placed on public property and who is paying for the propaganda and marketing of this bond referendum? Im curious if it is coming out of the same budget asking for more capital. If so, can we place our favorite politician or local business yard signs on public school grounds. All honest questions we are not getting answered before this enormous money grab “For the children”. We are in a rush for state support, but it looks like a mismanagement of long term capital planning from school leadership. How did we get in this position and can money solve it?
