Right, turning out your people is huge, and it becomes more rather than less important as margins are thinner which is a consequence of trying to gerrymander a thinner majority.
If Republicans turn 2 places they win by 130:100 plus a big city they lose by 100:130 into three they expect to win by 120:110 then if on the day Democrats turn out as usual but about 10% of the Republicans stay home across the board they lose all three 108:110.
My concern in the 2026 cycle is that there just won't be fair elections, and so this doesn't end up mattering.
