Harris will not be the Dem's candidate. She will experience a bump like Fiorini did in the Republican debate, but it will go back down again.
Biden is showing signs of senility, and that coupled with his propensity to be the King of Gaffes ends him before Iowa.
I tell you all, much of what is happening has been choreographed for the benefit of Clinton, to dilute the vote for Sanders. Think about. Castro wants to provide abortion for trans men. Now there is a real issue. And Booker, he announces we need to pay more attention to the trans population, a group that is 1/10th of one percent. Ah yes, another compelling issue.
Believe me, many of these smucks stay in to dilute the vote for Sanders until Clinton is far enough ahead and they drop out. There is no way the Dems nominate a communist like Sanders.
