Imagine the FUROR that would occur in the Senate if it were the DEMS who REFUSED TO ALLOW WITNESSES/DOCUMENTS? Should they?

Tell the SENATE they MAY NOT bring in exculpatory evidence/witnesses and see if reverse psychology will work on them as it always works on teens. Tell them no and they will do it. Tell them yes and they won't do it. Perverse is always irrational and irrational always loses.
