So couldn’t I go and fake-register 500 folks...get the four $25 vouchers each, then flip/sell them to some fake foundation (for 20-cents on the dollar) who’d flip them to special candidates?
Probably not.
But maybe you could run for office (or every elected office in the city) and promise to pay each person who gives you a voucher a 50% rebate. Then you get cash and they get cash and everyone (getting cash) is happy.
