Is it her presentation? Her discussed policies? Which ones or all of them wrapped up no matter how many are agreed or disagreed by people? Politicians that supported her despite their massive brawling back in 2007 and 2008 during that campaign (which was brutal, look it up). Misunderstanding by the public? Wikileaks' content? Wikileaks' content being forgeries? Has Wikileaks' content been addressed or contested? Trump was told by Rubio not to use Wikileaks, so he did say all but the W-word when going after her in debates, with summaries but avoiding detail (so now he looks like foolish since he believes the audience will lift even a single finger just like how they don't for every other candidate...) Unless he actually said the W-word at one point? All Democrats and many independents seem to subconsciously know she should have been a shoe-in, she honestly should be especially all of Trump's antics (and how the media has ignored some of her purported incidents) being put out by the media, and yet even today she's only a mere 5 points ahead, not counting for any margin of error. And that's just polls.
