Will Musk's rightward shift make EVs more popular with conservatives?
And if so, maybe there will be more electric cars driven overall?
Are you sure they aren't already?
Red State EV incentives (or lack of them) might be a bigger factor.
I believe "peto-masculinity" (not my term but I feel it accurately captures the phenomenon see Cara Daggett) overrides the desire to be a Musketeer.
A lot of conservatives live in rural areas, where EV range and lack of suitable chargers is a big drawback. Towing capacity and winter driving are also issues (tires and battery capacity in the cold). Probably those matter most than the politics of the manufacturer. A lot of car companies make EVs now...
