She made some mistakes, sure, but in the end, what criticism can you level at her?
She, or the people she hired to run her campaign, didn't think electorally enough.
Probably true...
I think Comey did her in... one has to think if he only affected 1 out of 100 voters in PA/MI/WI to vote for Trump or withhold their vote for Hillary or not bother to show up to vote for Hillary or whatever.. well that was more than the margin of difference...
Do I think Comey affected 1 out of 100 voters in those states.. you bet..
However, it is true that it need not have come down to that...
Free trade is a complex issue...it is hard to know exactly how to have handled it better.... certainly she made some missteps but compared to Trump...
My personal belief is that her campaign had tons and tons of polling from PA and some from MI which showed them to be comfortably in the lead.. and they were trying to expand the map instead of consolidate those states...in the last few days things shifted.. Comey was a big part of it...suddenly you found Hillary and Obama in Michigan.. and Hillary closed in Pennsylvania.. they knew they had a problem but by then it was too late...
