"Every voter should put a 55-cent stamp on his or her return envelope, no matter if it is already pre-printed with bulk postage by their election board. Political organizations, political action committees (PACs) and community groups should buy 55 cent stamps to distribute for mail-in-ballot return. A 55-cent stamp automatically overrides other lesser postage on the envelope and forces it to go first class -- hopefully arriving in plenty of time to be counted."

spread the word!!
(drop boxes are still the safest, if they are in safe locations.,. mine is in a library and manned by 2 election people)
