WASHINGTON (AP) — Democratic presidential candidate Kirsten Gillibrand has announced a plan to give every voter up to $600 in vouchers to donate to a spate of federal candidates.

But those candidates accepting such contributions would have to forgo contributions larger than $200 per donor.

The New York senator's "Democracy dollars" would provide every eligible voter $100 to donate in primary elections and $100 in general elections to presidential, Senate and House candidates.

Candidates accepting them would have to agree to a $200-per-voter cap on individual contributions. That's a significant drop from the current per-donor limit of $2,800 in primary elections and another $2,800 in general elections.

Outside political groups aren't subject to contribution limits. But Gillibrand and other top Democratic 2020 presidential candidates have vowed not to take donations from such groups.
