Pennsylvania’s candidates for U.S. Senate, Democrat incumbent Bob Casey and Republican challenger Dave McCormick, have sparred over energy policy since the campaign began. In his ads, McCormick has sought to paint Casey as anti-fossil fuel and to tie Casey to Vice President Kamala Harris’ old comments against fracking. Casey has maintained his support for fracking and an “all of the above” energy strategy that includes both fossil fuels and clean energy investments, like those made possible by the Biden administration’s Inflation Reduction Act.
