Maybe in the short term, since there’s not much the governor can do to affect rates except short-term spending. In the long term it would matter because the Republican supports Trump’s arbitrary & capricious revocation of permits for offshore wind, which could help lower energy costs in the future.

Very satisfying to overhaul the bike I ride everyday. Everything wore out at once, so I replaced the front rim; tires; grips; brake pads, levers, and cables; and chain. Rides like a dream now!
