Stop Bernie!

“If we spend the next four months tearing our party apart, we're going to watch Donald Trump spend the next four years tearing our country apart,” Klobuchar warned.
She’s right. The winner of Tuesday night’s debate was Trump.
Sad, but true. But how do the Democrats stop the food fight?
A Sanders nomination is a sure-fire loser, but how can he be stopped? Yes, Bernie "can" win, but the odds are against it, and it's more likely he will lose us the House also.
This is the Democratic "moderate" position and I'm sticking with it.
