I've written to Senator Barrasso and my state's two Senators about Barrasso's anti-EV Bill (discontinue tax credit and add a tax on EVs): https://electrek.co/2018/10/10/republican-bill-end-federal-tax-credit-for-electric-car/amp/. Perhaps the rest of you (US Citizens) should do so too? https://www.senate.gov/senators/contact.
