I think the fact that the DNC was backstabbing Bernie (per WikiLeaks) there will be a lot of super lib voters who stay home on election day. The anger that people have about her being above the law, as well as her lax approach as Secretary of State will incite some to vote who would not have otherwise voted for Trump.
A little here and a little there and we can nip at her vote count enough. While it is true that she seems to presently be above the law, she is not above ticking of the voters enough to make it impossible to cheat for enough votes.
Just my firm opinion...
