Bob Woodward warns 'there's not a great deal of hope' if voters back 'chaos and nervous breakdown in the White House'

Veteran journalist Bob Woodward, who recently published an inside look at the dysfunctional Trump White House, said he doesn't understand why anyone would vote Republican in the midterm elections.

The author and reporter appeared Tuesday on MSNBC's "Morning Joe," where he said GOP congressional wins would open another dark chapter in U.S. history.

“There's not a great deal of hope,” Woodward said. “If Republicans do well or hold their own, what are they voting for? Are they voting for the chaos and nervous breakdown in the White House or are they voting for local candidates and it can be some of both?”

He isn't sure what will happen in the election, but he said voters are making their decisions based on the president.

“You think it's going a certain way," Woodward, said, "but leave the door wide open for going the other way, and I think that’s the right approach because no one knows what Trump’s emotional impact he’s having on people. Lots of people don’t like it. There are a lot of people who do like it.”
