Here's an idea. The Minister does shit so let's nominate the one who caused this aka Theo. He's the one most likely to fight anyone in charge so he can fight himself.
It's not like we're doing anything. We got the brooms done because of me and Lucius and the wands because of Mr. Potter and Roxanne. Nothing else is really that important or relevant, so why are we stressing? Don't have a minister for a few weeks or months. Nothing will happen.
