New Minister for Magic

[Arya]

No: HPFGUIDX 96436

I'm been looking through the various History of Magic tidbits we've 
got and searched the Lexicon but found nothing on what we know of HOW 
a new Minister is empowered.  Since we know that Fudge will somehow 
(hopefull in some grand display of his idiocy) be leaving the office 
vacant, I've been wondering how the new Minister will come into 
office.  We've got the Wizengamot thingy, heresay that Crouch, as a 
head of the MLES, was on track to be the next Minister until he 
shipped his own son off to Azkaban...   

Do you think the Wizengamot just names the new Minister?  Does the 
Wizengamot put forth canidates for public election?  Does the public 
get a free campaigna and election and total control of the whole 
thing?  Is "Junior Undersecretary to the Minister" like second in 
command and likely to take over if the Minister is incapacitated or 
killed or is this Jr basically a glorified coffee-fetcher, arse 
kisser?  

Wondering,
