While contemplating the issue, it did come to my attention that we who are right leaning may be missing a point, test this idea and see if my guess is correct.
As we watch Fox, Real America News...or another more 'on the right' news source, we hear the use of her initials (AOC) often... I don't recall the
left,or at least the far left, using that same abbreviation.
With most of course, just the last name or.. a short, familiar name, such as Trump, or Eric Trump, comes easy and convenient. .
But when it comes as she insists, with triple names involving a hyphen..an abreviation seems to be invited.
Perhaps the left uses the entire name out of respect ! ??

!
Does that sound logical?
