It is somewhat odd to me that the Search Committee came with 7 names (not including Dr. Egger), but the electors then re-placed him into consideration and in fact brought his name forward rather than any of the 6 others the committee named. It is entirely possible that Dr. Egger indicated to the committee a reservation about being put forward, but subsequently changed that stance... this would probably be the least eyebrow-raising explanation.
If the electors chose to re-place Dr. Egger's name into consideration after the search committee had decided not to for any other reason, that would be a bit of a red flag organizationally, no? Consider if it were a congregational call - the call committee rules out a nominee, but the congregation votes him back onto the list. Nothing illegal or untoward has happened. But it would raise the question of why the congregation believed the call committee (who would be privy to a greater level of information and exploration) had erred.
Thus, there is a totally legitimate reason to wish for a more transparent level of communication.
Meanwhile, unless one simply feels, "Gosh, both guys are equally great and I can't see any advantage to one or the other," I don't see anything wrong with saying that Dr. Lehenbauer has a greater length and breadth of experience within Synod's highways and byways. It doesn't have to be read as belittling Dr. Egger, and it doesn't guarantee a better job as president... it just points out something the candidates' CVs make obvious.
*NOTE: since I entered the synod by colloquy, never took a single credit hour from CSL, and have never met either candidate, I really don't have a dog in this hunt. I want the seminary to excel and have no informed opinion about which candidate is more likely to bring this about. Whomever is elected will have my prayers and support.
