USW International President Leo W. Gerard says the recent U.S. Supreme Court ruling allowing unlimited corporate spending in campaigns is very troubling.

In an interview with the FOX News Network last night, Gerard said the decision opens the doors for a flood of big business money in politics. Click here for more from the FOX.

"The four largest Wall Street banks, if they expended one-tenth of 1 percent of their resources in a political campaign, that would eclipse every single penny of union revenue for every union in the country," Gerard said.

Gerard said the decision has concerned a lot of people and reiterates the need for public financing of campaigns in the United States.

“We need to move to public financing of elections. Otherwise, people will get cynical about their votes and will believe participation doesn’t matter," he said. "The vote of the make-up girl in the Fox studio, the teacher, the librarian or steelworker should matter as much as the banker. If people believe the voice of money speaks louder than their vote, they won’t participate in elections. We have to fix this.”
