A South Dakota lawmaker is pushing to close a campaign finance loophole during this legislative session. Senate Bill 12, introduced by Republican Senator Michael Rohl, seeks to cap the amount of money that can be loaned to a candidate or Political Action Committee (PAC). Rohl, who has criticized PACs as “personal checking accounts for the ultra-wealthy to buy politicians,” says the bill is part of a broader effort to improve government accountability. The 100th legislative session in South Dakota officially kicked off yesterday.
