Normally I couldn't care less about first ladies. They are fine. Laura and Barbara Bush, Michelle O...who cares. Hillary got wrapped up in some policy issues, but she was generally pretty irrelevant, too.
And Melania is probably just an irrelevant twit...but that is not why this is bad. It's a sign of a White House in chaos. That's why this is disturbing. How did her PR people not talk her out of this? Why did she go to the press instead of, oh I dunno, her husband? What the hell is going on? Has Trump really essentially cut himself off from his staff, as is being reported, and the only way you can reach him is through Fox News?
Lots of speculation, and lots of leaking, but who knows.
That's why this is bad.
