Let's pretend, for the sake of discussion, that DUmmies get their way, and Bannon is convicted. Then what?
1. Bannon appeals.
2. DUmmies howl.
3. Bannon still does not testify before Pelosiroo's Kangaroo Klown-Kourt.
4. DUmmies howl.
5. Rs win the majority in the House
6. DUmmies howl.
7. Rs shut down Pelosiroo's Kangaroo Klown-Kourt, making the subpoena on which the conviction was based, moot.
8. DUmmies howl.
9. Bannon adds this fact to his still pending appeal.
10. DUmmies howl.
Obviously, points 5, 7, and 9 are my speculation,
. But even if the Rs do not win the majority in the House, Bannon's appeals will tie up his case for a year or 3, and he will have as many months to expose the subpoena as partisan revenge, in court and in public. And DUmmies will keep on howling, because that is what they are.
