Hillary Clinton declared¬†on the sixth anniversary of the Supreme Court’s Citizens United¬†decision that as president she would¬†“fight to create a robust small-donor matching system.”

Clinton¬†previously endorsed such a system¬†for congressional and presidential candidates as part of her campaign’s platform. While Clinton hasn’t laid out any specifics, almost all House Democrats have co-sponsored the Government by the People Act, which would match political donations up to $150 at a six-to-one ratio with public money. For example, a donation of $100 to a candidate would be matched with $600, so the candidate would actually receive $700 total.

A similar system is already in place in New York City for mayoral and city council candidates, and¬†in fact has, as Clinton wrote Thursday, made it possible for people with “a passion for public service [to] run without having to court big donors and special interests.”

A recent poll found that 72 percent of likely voters favor¬†such a system, including 66 percent of Republicans. If small donor matching funds were available today it actually would give a much bigger boost to Bernie Sanders than to Clinton, with Sanders raising $250 million to Clinton’s $150 million (assuming Clinton continued her current strategy targeting big donors).

Clinton’s endorsement of small donor matching funds is arguably significant¬†whether or not she becomes president, given the evidence that most people are influenced by the positions their perceived leaders take, rather than reasoning through each issue individually.
