Right but the two people speaking up are you and Ms. Patil and you just got here. I don't even trust you, because I don't know you enough to judge what you will and won't do. So yes, any person nominating himself will get elected because they don't care, but let's not pretend that anything will work as a ministry. At best we'll go back to the start, when everyone was doing his thing.
You also have the problem of the DMLE now, I'm basically the only person in the Wizengamot.
I'm sorry, but I can't see a solution right now. You pick someone like your grandfather and you have a war with Hogwarts, because there's no way Severus will let it happen. You pick me, your grandfather will start his own war. There's so much baggage, distrust and infighting that I'm back to convincing your father to take the job back.
