Trump will capitalize on his reputation as a truth-teller, and be vicious about both Clinton’s sudden changes of position (e.g. the switch on gay marriage, plus the affected economic populism of her run against Sanders) and her perceived dishonesty. One can already imagine the monologue:The article goes on to say that some of this is fair and some of it isn't. The only one that isn't fair is the hit on Iraqi WMD. She really did say it, but there really were WMD. That won't save her, though, because her own party's partisans have spent so long convincing the American people that there never were.
“She lies so much. Everything she says is a lie. I’ve never seen someone who lies so much in my life. Let me tell you three lies she’s told. She made up a story about how she was ducking sniper fire! There was no sniper fire. She made it up! How do you forget a thing like that? She said she was named after Sir Edmund Hillary, the guy who climbed Mount Everest. He hadn’t even climbed it when she was born! Total lie! She lied about the emails, of course, as we all know, and is probably going to be indicted. You know she said there were weapons of mass destruction in Iraq! It was a lie! Thousands of American soldiers are dead because of her. Not only does she lie, her lies kill people. That’s four lies, I said I’d give you three. You can’t even count them. You want to go on PolitiFact, see how many lies she has? It takes you an hour to read them all! In fact, they ask her, she doesn’t even say she hasn’t lied. They asked her straight up, she says she usually tries to tell the truth! Ooooh, she tries! Come on! This is a person, every single word out of her mouth is a lie. Nobody trusts her. Check the polls, nobody trusts her. Yuge liar.”
UPDATE: An encyclopedia against Clinton from the Daily KOS. The only issue on which she looks better to them than Bernie is guns -- where Bernie looks better to me.
