I've discussed several times why we need PR in Congress (and if I haven't ask me to explain or fire up www.fairvote.org). I therefore suggest that the following ideas be implemented (warning: constitutional amendment required) for the two houses of Congress:
The House has 500 members, elected in 25 districts of 20-members each. Within each district, the 20 members are elected by the open list system; that is, individual candidates form unordered party lists before the election, and voters vote for a list as well as for a candidate within it. Lists receive a number of seats in proportion to their vote totals, and within each list the N candidates with the highest vote totals are elected (with N being the number of seats the list receives). Excess votes are distributed on the basis of largest remainders, so if before rounding the five parties contesting the election receive 6.2, 5.3, 5.2, 2.1, and 1.2 seats before rounding then they won't get 6/5/5/2/1 seats respectively because that ttoals 19 and not 20, but 6/6/5/2/1 respectively because the second party has the largest remainder.
The Senate is elected much in the same fashion it is today, but with three important changes: - There are 50 Senatorial districts based on population, not state boundaries - Senators have a term of four years, so that voters in each district may vote for a Senator in every Congressional elections - Senators are elected not by plurality or majority, but rather by either approval vote or Condorcet (IRV has too many flaws)
Now, the districts themselves are drawn according to the following guidelines (this is meant to eliminate gerrymandering as much as possible, obviously): - Each House district is made of the conjuction of two adjacent Senate districts - Each House district must include between 3.8% and 4.2% of the voting age population, and each Senate district must include between 1.8% and 2.2% (I give the Senate districts more flexibility here because they elect only one candidate each per election) - Senate and House districts must be geographically contiguous; Alaska is considered bordering WA, ID, and MT for purposes of contiguity and Hawaii is considered bordering CA - Senate and House districts must conform to county boundaries, except when it clashes with the population ranges given above (i.e. LA County has to be split between two Senate districts) - Senate and House districts should conform to state boundaries whenever possible - Senate and House districts should be as close as possible to culturally contiguous (e.g. separating downstate from upstate NY) and making sense geographically (e.g. using a mountain range as boundary)
Now, redistricting is done 13 weeks before elections if and only if a district has left the allowable population range since last redistricting; if a Senate district has left the allowable range but its House district has not, then only the boundary inside the House district is redistricted. If a House district has left the allowable range, however, then there is House as well as Senatorial redistricting, as long as the number of House districts whose boundaries change and the total area and population ending up in a different district are kept to the minimum possible. Note that Senators may end up serving slightly different constituencies before and after their mid-term; therefore, districts keep their numbering and are not scrapped every two years, although they may gradually "move." To illustrate the idea of moving districts, take Oklahoma, whose population increases more slowly than the national average, and Texas, whose population increases more quickly. Since Texas is gaining districts (the 1990 census would've given it about 1.84 districts, whereas the 2000 census would've given it about 1.94), it becomes denser, and thus districts "move" slightly in its direction. In non-census years, the redistricting is done on the basis of estimates.
Any thoughts (damn, this is already too long)?
