well it is more tied to party....Jane may lose her seat...If she is lower on the party totem pole.....but that may make the party as a whole less popular so they may be wary of dropping her. There are hybrid systems, but I find them to be more complicated. In general tho, minority viewpoints/parties are better represented in PR systems.
say a state has 10 reps allotted to it
going into an election both major parties have 5 reps
if the republicans gain major, broad based support, to say 70%,
under current system( with fair districts) you can expect Republicans to win all 10 seats.
under PR they would win 7 seats and Democrats would still maintain 3
as I outline, and I think in most PR systems, determination of the 2 Dems dropped would be up to the party
Right. And I would absolutely HATE that system.
Basically what you are saying is that we would no longer be voting for our Representatives, but rather for a party.
I HATE party. The label "republican" means absolutely nothing.
There are Republicans that are more left-wing than Obama. And there are Democrats who are more right-wing than Ronald Reagan.
So we all go out and vote, and reject the socialism, and vote 70% to 30% for Republicans.
The Democrap party arbitrarily eliminates the Cheri Bustos, Ron Barber Conservative Democrats, and fills the 3 seats with Pelosi, Waters, and Biden, the most liberal.
Then the Republicans party, chops off the Reagan, Palin, and Thompson, conservative Republicans, in favor of McCain, Romney, and Dole, Liberal Republicans.
By giving the power to choose who ultimately gets our votes, to the party, the result is, it is entirely possible for people I would NEVER have allowed in government, to get a seat because of my vote.
If I could know ahead of time that my party would put Dole, Romney or McCain in office ahead of Reagan, Palin, or Thompson, I would have voted for the democrats, or a 3rd party.
This is exactly how I have heard proportional voting described in the past, and honestly, as flawed as districting is, I would perfer that by miles, over some party telling me "thanks for your vote. Now we'll put in whoever we feel like".
