Imagine, for a moment, that you didn’t need to raise money to run for office, that the government would pay you to run. Who would that help? Would it encourage more moderate candidates, who are usually pressured out of nomination contests by party money because they don’t stand for anything? Or would it enable the extremists, whom are normally de-funded due to concerns about their toxic views?
These findings suggest that it’s the more ideologically extreme candidates who take advantage of clean funding to run for office. Under the traditional funding system, party donors function as gate-keepers, reducing the power of extreme candidates by channelling money away from them. Take away the gate-keepers, and it’s the extremists who break through, contributing to the polarization of the legislature.
