Most any Democrat who would run for POTUS would. Maybe sneakily, quietly, by strangling it through costs associated with regulations but kill it they would.
My question is starting from Reagan (after the Carter 55mph fiasco, etc) through Bush, GW - we could already have had it. GW Bush was talking saw grass to run cars while the media said he was in bed with his oil buddies. I wonder how soon after Trump’s second term and a Democrat gets in will all this be shut down in the name of global warming/climate change.
