I knew that, and of course the LDP is gaming the system to benefit themselves, they're the LDP. I was just wondering if the party (or rather their coalition with Komeito) would achieve successive majorities if constituencies were apportioned to a minimal deviation standard.
Oh, oh, you were talking about a hypothetical. Forgive me, it's quite late
I do think you're right, the majority is large enough that they'd be home free even if the seats weren't so lopsided. Of course, Russia last year gave us some insight into what that might look like, and it seems the answer is just hideously blatant gerrymandering.
Oh, and you're right in saying the LDP-Komeito coalition rather than the LDP, because they do actually stand aside for one another in the FPTP seats, hence why the Komeito almost never get more than about 2% in that vote despite regularly polling five to six times that in the PR vote.
