A general rule of thumb in professional fighting and in professional wrestling is to never talk down your opponent too much because if you win, you just eat someone who you should have beaten easily. If you lose to the person you have been denigrating, you just lost to someone you should have easily beaten.
Right now I've read Hillary is evil, a liar, a con artist, a corporate shill, a warmonger who wants to kill brown people, a Republican who's masquerading as a Democrat amongst other falsehoods. There is no way anyone with zero positive qualities should be winning a political race.
Now if Hillary is half as bad as her detractors make her out to be then why is she winning and winning quite handily? Right now she has a 96% chance to be the Democratic nominee in November. She has a +225 delegate lead last I saw and I believe close to a million vote lead for the pointless who has more votes total. Even assuming current polls are correct for Mega Tuesday Hillary’s delegate lead will hold and make it harder for a Sanders path to the White House. If you believe all the negative things said about Hillary then the only question left is what does that say about Bernie Sanders who is losing quite handily to Hillary Clinton? If Hillary is the worst politician in the world then what does that say about Bernie Sanders who is losing but according to the series of tubes we call the Internet should be winning yuuuge? And this is the conundrum of saying how bad Hillary is and never acknowledging her positives and why people would vote for her,. By not doing that you make your own candidate look worse because he is so far behind her in every political metric where the people decide between the two.
