"Vote for 2" is a standard, well-accepted method for choosing two winners. And a runoff is the standard, well-accepted method for deciding between two candidates. So I propose to combine those two steps into a single election.
Right, well, that's an interesting point. If Vote for 2 then Instant Runoff can be sold to Joe Sixpack on account of its being based on well-accepted methods, but Approval cannot, because it is novel, then getting something better than FPtP/IRV in place may be better than nothing, in helping to replace the omnicidal regime with a people's regime.
