I think they will vote it down narrowly (I think Nancy has the no votes). This allows them to have their talking points for the campaign and the media without ever getting to the trial and being put under oath.
Because if they do - they are screwed. They will all be put under oath and forced to take the fifth. NONE of the senators who are on the campaign trail will be allowed to talk about it - because for 6 days a week - 6 hours a day they will be forced to be sitting silently in the Senate.
Do you think that is what they want Warren doing? LOL
