I am not touting a multi-party system because I expect it to shift the spectrum more towards the center, though it might. I have not mentioned anything about shifting the spectrum at all, so telling me that something I never said makes no sense - makes no sense. I am touting a multi-party system because it is infinitely more democratic and representative than the US two party one. It really is very simple and just basic common sense.
I agree, PR makes no sense under the current US system. But, PR also achieves a much fairer representation of the wishes of voters, at least there where voters have a choice.
I have never claimed that gerrymandering 'only' benefits Reps. Don't presume what I may have 'conditioned myself' to think. I'll give you some indisputable facts, though - facts that the Reps either feign ignorance about, or simply ignore when making the specious claim that you have made here.
The facts are that gerrymandering benefits Reps FAR MORE than Dems. It is a fact that this vile practice has enabled the Reps to thwart democratic election results and produce an unjustified and undeserved Rep majority in the House on a minority of the popular vote! Here are some more facts for you.

So yeah, gerrymandering benefits both sides.
And for sure, the thoroughly rotten and corrupt US electoral system must be preferable to one of those suspicious foreign inventions, a multi-party system with PR, where the big money that subverts and perverts all of US politics has been removed from the electoral equation.
