The article's summary paragraph at the top attributes a statement to DeSantis that he didn't make.
Gov. Ron DeSantis says people aren’t living as long as they used to, so that should help protect them from losing Social Security and Medicare protections when they get old.
That paraphrasing is deceptive, IMO. In the text of his remarks, it's clear that he's drawing an actuarial conclusion that lower lifespans eliminate the need to raise Social Security and Medicare benefit ages. What he actually said:
So, I think it’s hard to say, you know, raise the age (for Social Security eligibility) when the average life expectancy is going down. We used to think that life expectancy was just going to keep going up and that’s just not been the case.
DeSantis says plenty of crazy shit, we don't need to invent stupid things and pretend that he said them.
