Huh? Biden already stated that his lackluster climate bill was "once in a generation". He's approved more drilling permits than Trump did. Why would I be under the impression that he's any less pro-oil industry?
Biden could pass the most draconian, fascist border policy or whatever (like he offered to do for the GOP) and Trump would still claim he's going to undo whatever Biden did.
That anyone would put stock in Trump's meaningless babble, as if he's ever talking about something real, is frankly depressing.
