A lot of what Bernie Sanders says about climate change is sensible. His comment at the last debate that global warming is our biggest foreign policy challenge sounded untimely in light of the present circumstances, but in the long run, he may well be right. His proposal for a carbon tax, and for targeted spending to mitigate its impact, is also perfectly reasonable, and you can make a case for his suggestions about new regulations.
Unfortunately, however, he insists that the root of the climate change problem is the overweening power that fossil fuel industries wield in Washington. There is no doubt that coal and oil interests are influential, particularly in the Republican establishment, but the responsibility for using their products falls on all of us. If you could somehow banish all oil lobbyists from Washington, people in this country would still be buying SUVs, and there still would be no economically viable alternative to the use of fossil fuels in a variety of different contexts.
I suppose the next thing he will say is that Big Soda is forcing sugary drinks down my throat. This is the caricature of the nanny state that pushes people who might otherwise know better to vote GOP.
