It’s not ironic necessarily. It’s more the morons that hated EVs and Musk hated them because Trump did. Now that Trump loves them, they love them.
They’re just weak-minded easily manipulated sheep who hurt when they have to think for themselves and they’d rather be told what to think.
Trump is all about removing regulations and stated “for every new regulation, 10 must be revoked.” During his first term it was 2. He is moving the market that way, and boy oh boy is it going to suck for the consumer and small companies that want to compete.
