This poll is just liberal media propaganda. All the guys in my local bar and my 2,0000 great, great ,great, great, great, great, great, great, great, great.....grandma who has never voted for a Republican are voting Trump. But look at the rallies. The rallies. That's more scientific than polling.
The problem both have is they are well known by the public. And well disliked. Nothing either can do to change people's perceptions of them so this will be an event election.
However, Trump does have an uphill battle. If he can't pass her, assuming these polls are correct, after what happened in Orlando then I don't know what he can do
