LCMS Presidential elections can be full of drama and suspense.
Here are 3 of them which can be classified as surprises:
In 1969, Jack Preus defeated incumbent Oliver Harms by less than 5 votes.
In 1992, Al Barry defeated incumbent Ralph Bohlmann by 12 votes.
In 2001, with no incumbent on the ballot, Gerald Kieschnick won by 18 votes.
I thought President Harrison's win in 2010 was a surprise - especially considering President Kieschnick's success with the BRTF proposals.
Having been a delegate to the Houston conventions (2007 & 2010), my take was/is that 2010 wasn't as surprising as some might've thought. IMO, it was the culmination of many things that had been building since Pres. Barry's death just prior to the 2001 convention. Those nine years packed an awful lot of things that contributed to the reaction that resulted in the, for lack of a better descriptive term, "Issues, Etc. Revolution". I recall hearing (perhaps overly wishful thinking) rumors of Matt as early as that 2007 convention.
Oddly enough, I think that LCMS convention floors like to engage in some ironic, almost Faustian, gamesmanship - to wit:
*1969: Fellowship with ALC paired with Jack Preus
*2010: BRTF paired with Matt Harrison
We've always been an interesting bunch...
