Was the email thing a dumb, tedious, over-exaggerated scandal? YES.
Was the Comey letter a despicable interference in the election? YES.
Did the Comey letter cost Clinton a few points in a razor-thin margin election? YES.
Was the Comey letter the only or even the major reason why Clinton lost? HELL NO.
She was running flush with cash against Donald freaking Trump. A generic Democrat in her shoes should win by Obama 08 levels.
1) It's a testament to what a horrible candidate she is that she lost
and
2) The Democrats had no business crowding out the field, then nominating a candidate with such potentially toxic downsides.
Yup, I think that is a more balanced perspective.
Hillary is insulting our intelligence if she thinks that cost her the election. Never underestimate our ability to smell a thinly veiled excuse.
