Libertarian presidential nominee Gary Johnson left Boise Tuesday after a Monday campaign event with another $73,692 in public financing in his campaign chest.

The Federal Election Commission on Wednesday said it certified the payment Tuesday, bringing the total received by Johnson to about $304,000.

President Obama and Mitt Rommey have rejected public financing because it would limit how much they can spend on the race. So far, about $500 million has been contributed directly to presidential candidates in the 2012 cycle.

Obama has raised $300 million in direct contributions to his campaign, Romney $151 million. But Romney has out-raised Obama the past three months and and is getting more support from independent expenditures. The Republican National Committee is also raising money at a faster clip than the Democratic National Committee.

The Democratic and Republican parties will receive $18.2 million to fund their national conventions.

The presidential public funding program is financed through the $3 check-off that appears on individual income tax returns.
