The system is rigged, but in a more subtle way. A good chunk of our elites have effectively used their offices to attack and undermine the security posture of our voting system via public policy. They aren't buying votes, they are creating the basis for an asymmetric threat in the form of lowering the security sufficiently to make it easier for bad actors to infiltrate the process. They do this by attacking any measure to seriously authenticate people claiming to be eligible to vote. We have states that actually issue driver's licenses to illegal immigrants as a matter of public policy. They then allow those same licenses, given to people who federal law doesn't even allow to reside in their state, to be used to identify voters.
Fact is, these politicians, activists and lawyers support voter fraud. You can be confident in that simply by following their priorities. Increasing access to public resources is a passion of theirs in every area except IDs. They're most certainly not libertarians who believe no one should be required to carry and prove ID in public. They hate efforts to actually force security on the process precisely because it would lower the asymmetric threat to the system, and that threat tends to vote in their favor.
