The SAVE Act is a misogynistic, racist, anti-poor horror bill. Of course, that self-obsessed trash ogre John Fetterman says he will vote for it.

SAVE Act explained: Republicans' sweeping elections overhaul would impose strict new voting rules, potentially disenfranchising millions of voters
The bill was approved by the House of Representatives, but faces long odds of being passed by the Senate.

Eliminating the endangerment finding on CO2 puts us at more risk. The finding enabled the federal government to treat carbon dioxide as a pollutant, making it directly subject to regulation. This move is a middle finger followed by a mugging. It will cost us dearly.

We are in more danger without "the endangerment finding" on carbon dioxide
It would be generous to say this is a “head in the sand” approach. It is really a middle finger followed by a mugging.
