If they need to make it a culture war thing, they could just call it the Keystone pipeline of electricity, or the Trump Powerline, or similar.
(As a non American, I may be misjudging this: I don't care too much about US culture wars, they don't connect to me any more than the US or Chinese sports teams whose names I don't know).
You may be correct that I am over-optimistic, though for what it's worth my optimism is not universal to all of the aspects of Musk let alone Trump (mostly pessimistic about him), and not with regard to other greenhouse gas emissions besides electrical, heating, and transportation.
