Oh, at first I was interpreting voting block as set of people with the same full preference profile. Obviously, since you are modifying RD, it should just be people with the same first choice, so my point doesn’t matter.
Unlike RD and ML, your proposal is not clone invarient.
For example, randomly sample N voters from the electorate, and run ML taking account only of those voters. Fails Condorcet, like RD, but it gives the behavior I specified. Politically infeasible, of course. And I’m not really sure I buy the argument-from-war for RD.
Something like squaring the size of each voting bloc before doing a weighted random selection? This gives a 90% chance for a 75% majority to win.
I don’t like this because irrelevant alternatives can split a voting block, and have a large effect.
