Trump certainly didn't lose the shitfest I watched. He was just part of it. Romney coming out today and doing what he did, that is a huge positive for Trump.
Trump, if the nominee, will crush Hillary. I'm pretty sure Sanders will be the nominee, not because of this email shit, but because nobody likes her outside of the old liberal segment of the party. I think within two weeks the big story will be "Sanders surging".
I'm not sure what the fuck happens then with a Sanders/Trump race, but I think Hillary would be absolutely crushed in the general election against Trump.
