The Hill:

Snowe and Sen. Susan Collins, her fellow Republican from Maine, co-sponsored the historic Bipartisan Campaign Finance Reform Act of 2002, along with McCain and a handful of other Republicans. But Collins's spokesman Kevin Kelley said this year that Collins would not jump onboard. He did not indicate the reason behind the decision.

Of course, the 2002 bill came up for a vote several months before the junior senator faced the voters.

Anyone else see a pattern here?
