Can I have some of that, whatever it is you’re smoking???
The left is aware that its brand of socialism is a hard sell in many parts of the country. They know they have to have certain advantages and manipulate things in order to win. It isn't that big a stretch, but you have to have been around as long as I have and gotten as cynical as I have about their intentions and their greed for power to even think it.
I think they would stop at nothing, including scripting the whole DNC nomination plot made-for-TV so that it captures all the media attention.
One thing that could be said to be evidence... was the stage in Colorado. I believe that stage was meant to transpose the Berlin event to America (via the columns imagery.. bringing up the image of the Berlin speech.) I don't think Berlin worked like they expected it would. For one thing it became the subject of tons of negative comments on talk shows, and so its effect was neutralized. If they scripted this thing, they expected to bring the payoff from the Berlin speech to the American stage as a subconscious image by recreating a likeness to the Berlin background. Crazy? No doubt. But it wouldn't surprise me. Nothing these people do surprises me anymore.
