They probably wouldn't, but by the same token, they (hopefully), wouldn't try to ramrod nonsensical solutions through that don't help reduce MMGW but instead, just punish consumers.Wonder what that party would look like. Bet they wouldn't deny manmade climate change. Regardless, we live in the here and now and have to deal with reality as given.
Hopefully, they would do the only thing, that we currently CAN do, to lower emissions, and that is nuclear power plants. That's it. That is the ENTIRE list of things that would make a measurable difference.
