Their problem is that the Clinton Machine and the Soros Machine have such complete control of the DNC that there isn’t any room for a real candidate to emerge.
So its Clinton or nobody. And you notice that no one except a no-name with no record has dared to run against her for the nomination. He was a fake candidate intended to make it look like a real race, but so unpopular is she, and so closed is the party to any real candidates in the party, that people have flocked to the fake candidate in droves.
That is their problem. It isn’t Trump, it is that DNC has been captured by Machine politics, and the only daylight is when the two machines turn on one another. Aside from that, there is no room for anyone else. No one within DNC dares to run against the Machines.
imo, the bern was intended to be merely a placeholder in the primaries to mike the hildabeast look "younger" and more "middle of the road".
