PHILADELPHIA (CBS)  –  The polarization of American politics is on display in a survey of House and Senate voting records on the environment.

The survey by The League of Conservation Voters compared pro-environment votes to all votes and came up with a percentage.

While Philadelphia’s Bob Brady got a 91- percent, highest among Pennsylvania Congressmen, Bucks County’s Mike Fitzpatrick got  46-percent, which the LCV’s Alex Taurel says is the fourth highest score of any Republican.

Taurel says, “The 112th Congress is the most anti-environment House of Representatives in history. They launch an absolutely full-scale assault on public health protections, on clean energy investments, on efforts to tackle the climate crisis.”

Taurel says his group hopes the National Environmental Scorecard is a tool for accountability, but its results can just as easily be read with numbers inverted if you’re in the mood to elect someone against government regulation.
