Speaking as an outsider here!

I remember hearing vox pop segments last time where democrats were saying that if Hilary got the nomination rather than their choice, they would vote Trump. Seemed odd to me at the time, but I could see it happening this time. Biden's campaign will, I think, label Sanders as such an extreme socialist who wants to take all of your money that I can see a lot of Democrats thinking they are safer with Trump. The opposite situation is probably less extreme, but if Sanders is labelling Biden as "pretty much the same as Trump" in terms of policies, I could see Sanders supporters saying it doesn't really matter who they vote for, then.

From here, it looks like near tie looks as if it could benefit Trump more than anyone. Please tell me I am wrong!
