For months, Bernie Sanders has made it known he's "with her."
"I have come here to make it as clear as possible as to why I am endorsing Hillary Clinton and why she must become our next president," Sanders said at a rally in July.

But a few of those are considered Democratic strongholds where Clinton is pretty far ahead.
