In Seattle we have Democracy Vouchers funded by the city that every voter is sent in the mail and can be used to make campaign contributions.

This led one candidate to hire people to solicit/collect these democracy vouchers. He raised over 350k from democracy vouchers.

When the election came around, far fewer people voted for him than contributed democracy vouchers.

And the program administrative and overhead costs are quite high, approaching the level of total funds distributed to candidates.

Just pointing out that handing out money isn't free (although it is one of the true core competencies of the US federal government), and can have unintended unproductive side effects.
