The relevance to this is that you asserted that Republicans haven't given themselves any electoral advantage at all or that, if they did, it accounted for less than 1% of their success, when that cannot be further from the truth.

You said "explain your reasoning", and that's what I did.

No need to get defensive over it and try to pretend like it's irrelevant to the discussion. This is literally the discussion you explicitly asked for. If you don't like the fact that the Republican party has acted in a decades-long effort to guarantee their own power in perpetuity with or without public support, don't get mad at me, get mad at them.
