Warren and Biden destroyed themselves by her lies and his incoherence.
But after 9 debates, the Democrats did not attack each other until tonight....and it was mostly aimed at Bloomberg.
No Democrat is being properly vetted for the general campaign where Trump will not hold any punches.
They think they should not attack each other, but it only produce a weaker candidate.
If Trump did not come out swinging during the RNC debates, Jeb would have been our candidate and we would have President Hillary.
Exactly right - by not airing their dirty laundry in the primary, the Dems allow it to be used for maximum impact in the general. And the media, by trying to help in that regard, hurts them.
