It's not even close to just leftists.
You think all those 10 of thousands of people going to see Bernie or the million plus donating to him are just leftists?
On top of that, look at an example of what the country will hear about Hillary.
When Hillary was SOS, Saudi Arabia wanted to buy 29 BILLION in arms from Boeing. Everyone from Iraq to Israel to even others in State said don't, it will destabilise the region. A few months before she signed off on the sale - which she called a "personal priority" - State released a catalogue of all the human rights abuses of Saudi Arabia. They also said that their military was being used to kill civilians.
On the other hand, Saudi Arabia donated at least 10m to the Clinton Foundation, and Boeing paid Bill 250,000 for a single speech.
Since that time SA has used those weapons, like the State Department predicted, and like our allies warned, against civilians in SA and Yemen, where they are - with out help - committing grave war crimes.
The other thing to note is that her campaign manager owns the lobbying firm that SA hired to make sure that SA didn't look bad in the US media. And that same lobbying firm - which has donated hundreds of grand to Clinton btw - also lobbies for Boeing.
Do you REALLY think her campaign can win when there's numerous examples like that that will be plastered in every newspaper in America? All while she refuses to release her transcripts from GS?
Its a disaster waiting to happen. The energized left knows this now, but the country will know soon..
