New York City’s campaign finance law also contains a vast carve-out for unions. In 2005, the CFB attempted to codify its practice of treating local union contributions as “single source” contributions. That is, each union was subject to the $4,950 contribution limit per candidate that applies to individuals.
Labor pushed back and got a bill through the City Council in 2005 that allows for nearly unlimited campaign contributions by unions. Each of many local union chapters now has the ability to make the maximum $4,950 donations as a separate entity—even though they all remain firmly under the umbrella of a single union.
