So Donald Trump's 2005 tax returns just 'show up' in one of her people's mailboxes, with no names attached. And she gets all excited, goes to press with it, and -- it just so happens -- team Trump is ready to release the documents themselves that afternoon in order to scoop her. And then she goes over the top, of course, trying to tie this to various conspiracy theories. Then the returns prove mainly that he paid a massive amount of taxes that year, hundreds of times more than the average taxpayer will pay in a lifetime of paying taxes.
I'll bet I know who mailed those tax forms to Maddow's assistant.
And now Trump is immunized against the whole "show us your taxes!" issue.
