and his tweet is still up
Not only is it still up, he's still tweeting
Pretty much, it's like the newscaster said in one of those super right wing news networks with "When I'm right, I'm right and when I'm wrong, I'm still right"His supporters won't care. Anymore than the followers of YTers cared when they repeated things they were told that were proven to be false. Time after time after time.
Once you sign off on foolishness, you have to ride for it. No matter how stupid it makes you look.
