I forgot about Barty Sr almost being Minister instead of Fudge. That would make sense. Without Voldemort gone (cause in Canon they don't go after the Longbottoms till after Voldie is 'dead'), it's not likely that the Lestranges and Barty Jr would get caught as easily. So yeah, I think we will have him elected as Minister. We'll play it out as we go if Barty get's suspected or caught after Senior gets elected.
