I realize they have to defend her, but sheesh.

I know, they look stupid doing so.
When you look at the way Maddow went about this, she failed from the very start.
Here's her original tweet, and pay attention to the way she worded it.

Rachel Maddow MSNBC @maddow
BREAKING: We've got Trump tax returns. Tonight, 9pm ET. MSNBC. (Seriously)
When she say's "we've got Trump tax returns" most people are thinking of the "current" returns.
Now she does try to disguise it a bit by saying "Trump tax returns" instead of "Trump's tax returns", but still I'll guarantee you most people are thinking of the katest returns.
So from the start she not only disappoints with the fact that this was an old tax return, but of course the content blows up in her face with the fact that Trump paid millions in taxes.
Imagine her leftist audience ready to pop champagne corks in anticipation of some really damaging news for Trump, but instead the return makes Trump look like a patriotic tax paying American.
