I think it's unclear if Musk fully supports Yang. He was obviously teasing a bit and 'support' is not the same as 'endorse'.

Agree, the article is just a re statement of Musk's tweet, which gives no detail about why he endorses Yang and a listing of some of Yang's positions.

Not sure how you create an entire article on an Elon endorsement of Yang based on a 3-word tweet, but here we are.

This article does a nice job of stringing together the series of tweets that makes this a truly newsworthy story. Although Elon's support was merely a tweet response to well known historian Dan Carlin, it shouldn't be considered an endorsement. I'll let it slide because the author, who likely know he was overstepping, gave himself some wiggle room by saying that Yang's policies "appear to have earned an early endorsement".

basically states what Elon tweets and explains hangs position so it’s a fair article
