The house already shot their wad, and have pissed off much of their base by fucking the impeachment up.
Round two would be too obvious, even for them.
They will simply dredge up dirt and use it against Trump from now until Trump leaves office.
There is no limit to their stupidity.
But they are vicious fighters and fight dirty.
They will pull up "evidence" and tell Americans how stupid they were for allowing Trump to remain.
