Former Sen. Alan Simpson (R-WY), who does work on behalf of Americans for Campaign Reform, was the subject of a brief "where are they now"-type article in National Journal this week in which he spoke about his desire to combat the corrupting influence of money in politics.
The piece is available only to subscribers, but below is the relevant excerpt:
Some things about Washington still bug Simpson. "I think campaign money has completely distorted the system," he holds. "If a person is going to give the maximum year after year, they are going to have access to a [candidate] in a way that's not wholesome.... Money corrupts."
Americans for Campaign Reform supports a voluntary full public financing system for Congressional and Presidential elections, and Senator Simpson and several other former members of Congress have lent their endorsement to the Fair Elections Now Act in the Senate.
