What does McQuade mean by "The Fix"?

Based on the provided Recapy summary, McQuade uses "The Fix" mainly to denote the way corruption, cruelty, and chaos are being weaponized to "fix" outcomes—i.e., to rig government and warp American democracy toward authoritarian rule. She also uses the phrase in the other sense—a call to fix the problem—because the book pairs that exposé with a practical roadmap (organizing, protests, running for local office, strengthening rule of law) for repairing and reclaiming democratic institutions.
