The prospect of Trump being a better president, and by contrast, proving to the world what a pathetic failure Obama was, scares the left more than anything else.
They know that if Trump is successful, it will demonstrate to the American people just how vacuous and empty the entire left wing agenda is. He is literally the most dangerous threat they have ever faced.
Yes that is Seriously how they see it, if they do not win this one they know he will triumph and they are so through that is why they cannot drop it, It is do or die for them,
The ‘left’ doesn’t like anything Trump does, because they are INCAPABLE of doing what he has, and they know it. Which is why they ‘hate’ him from their inner being.
