In 1995, senators John McCain (R-AZ) and Russ Feingold (D-WI) jointly published an op-ed calling for campaign finance reform, and began working on their own bill. In 1998, the Senate voted on the bill, but the bill failed to meet the 60 vote threshold to defeat a filibuster. All 45 Senate Democrats and 6 Senate Republicans voted to invoke cloture, but the remaining 49 Republicans voted against invoking cloture. This effectively killed the bill for the remainder of the 105th Congress.
