It matters in the rare situation where there is a vote occurring that straddles the start of the new congress.
This was actually a major controversy in 2010, because Bgwah or Bacon King or someone counted both the leaving members and the new members. This meant that some regions had 2 votes while others had zero.
That was when bgwah passed something like the 4,215,151 amendment to the proportional representation act to establish a clear line of succession for the Atlarge seats.
All incumbents keep their seats
1. Peebs > Peebs
3. NC Yankee > NCYankee
6. Leinad > Leinad
8. Rfayette > Rfayette
9. Weatherboy > Weatherboy
That leaves
2. Jake
4. RC
5. PMasta
7. Wxtransit
1. Appointees replace the one who resigned naturally Oakvale - Leinad
2. If there is a vacant seat held by a party member, and another member of that party is elected, then that person gets the seat.
3. If there are multiple incoming Senators of a given party, the first one to swear in first gets the seat. So Congrats Ninja, you get get seat number 2
Seat #2. Jake > Ninja
That still leaves RC, Masta and Transits seats and Sestak, Never and Dfw
4. For if a party loses seats, and there are no incumbents, the first of that party's elected members to swear in gets the longest held seat for that party then remaining ones would be distributed to the new members. This doesn't apply since no members of the Alliance won. IF one had, they would have received Transits seat.
5. not applicable since more than one seat changed hands
6. If a party loses multiple seats to more than one different party. I think 7 is more applicable because two parties lost seats
7. If more than one party loses seats to multiple parties, the political persuasion of the departing and incoming Representatives may be used to determine who is the successor. Seniority is the fall back if this doesn't work. (You know we never have had an election where we go down to seven.)
I was told by DFW that RC endorsed him as his successor something like that, if that is so:
seat #4 RC > DFW
seat #5 Masta > Sestak
seat #7 WxTransit > Never
Seniority would yield this
seat #4 RC > Sestak
seat #5 Masta > Never
seat #7 WxTransit > DFW
You know something told me back a month ago, that I should delete the first half of clause 7.
