Katco is not running for office.
Mastriano is bat shit crazy. Regardless of his stance on dark money, a vote for a Republican is a vote to keep Dark Money in our system.
From the office of Nancy Pelosi:
Congress must improve enforcement of campaign finance law, end the scourge of dark money and establish its authority to regulate the raising and spending of political money, by passing a constitutional amendment to overturn Citizens United.
If you are serious about campaign finance reform, vote Republicans out.
