There is no way that anyone watching that, especially Republicans, can possibly think the Dems have any case all. It was exposed as a naked political attack.
Again, if Bolton was so important to the Democrat case, why didn’t the House subpoena him?
Its a question to which they have no good, persuasive answer. Its not the job of the Senate to redo their case for them.
Which is bottom line - when all is said and done, they have no case.
