A Manhattan lawmaker says NASCAR provides more information about its sponsors than politicians do about their contributors, so he’s introducing legislation that would require pie charts showing where each candidate in a city race gets their money.

Councilman Ben Kallos said his bill would yield the “most transparent” information ever for voters in New York City.

The information would be easily readable in pie chart form and delineate special interest contributions, including contributions from real estate developers and lobbyists. The data would be made available by the city’s Campaign Finance Board, both online and in official voter guides mailed before elections to all voters.
