Politicker AZ has a brief post this morning about Congressman John Shadegg’s willingness to succeed John McCain should he win the Presidency. Shadegg is clearly the obvious and best choice for that seat and you won’t hear any objections from me. So I’ll leave that political contest as a given. But if you look beyond the successor of John McCain the vacancy left in CD-3 will place Arizona’s political chessboard in motion creating all kinds of excitement amongst politicos. State legislators (Waring/Gorman/Allen) and city councilman (Baier/Simplot) among others (Hatch-Miller) will scramble to jump in this race. School board members will scramble to follow state legislative seats and on and on… So I’m throwing it out to all you political observers – what kind of matrix can we expect to see when John McCain becomes President and John Shadegg becomes the next Senator from Arizona?
