The case when everyone agrees doesn’t tell you anything. It’s only when people disagree that you can find who has actual power and in this case the general public has effectively zero actual meaningful power day to day.
Systematic voter suppression plus gerrymandering etc may win you rigged elections, but ultimately voting isn’t about the system in place it’s avoidance unrest. We’re entering uncharted territory with how strongly people disagree with what the government is doing, which is where the general public actually has a say, namely by destroying the existing power structures rather than voting. It’s not even a question of insurrection, not having kids plus 60’s style dropping out at scale is ruinous.
