US Politics
Well, representative distribution is a big and complicated topic, but at the least we can simply say that the constituencies being represented are divided, even if we may have issues with the constituencies themselves.
CRS has a nice history of Speaker elections here. A member crossed the aisle in 2001, but generally members have always felt free to simply abstain, indirectly giving a hand to other candidates.
Either way, though, a stronger national consensus (of constituencies) would solve the drama. We don't have that, though.
