The House is expected to vote on the bill -- H.R. 3463, introduced by Rep. Gregg Harper (R-Miss.) -- Thursday.The groups acknowledge that the presidential public financing system -- which provides candidates with the funding to run a campaign -- needs to be adjusted "to respond to the increased costs of running a presidential campaign." But repealing it would make candidates indebted to special interest groups, they claim.
"In the aftermath of the destructive Citizens United decision, the financing of the 2012 presidential election is being dominated by bundlers, big donors, Super PACs, candidate-specific Super PACs, secret contributions and the like," the groups wrote in the letter. "This is the kind of campaign money that leads to scandal and corruption."
