According to this Democracy 21 press release, some members of Congress are working to change the public funding system for presidential elections. Apparently primary season matching funds would be abolished, and the money would be used to pay for the major party presidential conventions. This idea might appeal to Democrats, because the Democratic National Committee is low in funds that are needed to pay for costs of the 2016 Philadelphia convention.
The only minor party or independent presidential candidate who is currently seeking to qualify for primary season matching funds is Jill Stein. She must raise $5,000 in small donations from each of 20 states. She recently crossed the threshold in New Jersey and Pennsylvania, so is up to eleven or twelve states now.
The change in the law would be brought about by inserting provisions into the omnibus spending bill, which is expected to pass by the end of the year.
