It’s not just gerrymandering (though that is indeed pervasive and pernicious. It’s structural. The apportionment between states gives small right-leaning states outsized representation in both the house and senate relative to their proportion of the national population.

That's not a bad thing. The bad thing happened when the Democrats decided to alienate those areas and lost them. You may forget, but a lot of those "small right-leaning states" were solid blue until relatively recently. For instance 100% of North Dakota's congressional delegation was Democratic until ~2010, Iowa was the quintessential purple state, the Senate majority leader was from South Dakota (but unlike today he was a Democrat), and I could go on.
