  "description": "The data behind the chart “Iowa county early voting, through November 1” (post 21), as of 2026-11-03. ColdSpark county early-vote trackers; calculations by Carmena’s Overton. Separate tracker totals: UF Election Lab, CNN/AP/Catalist and NBC News/TargetSmart. Full-2022 early totals: CNN/AP/Catalist; 2022 turnout: OnPoint. Frozen November 3 graphic; Iowa through November 1. These are party groups, not candidate votes. Consistent voters voted in two to four preceding generals; occasional voters in zero or one. County comparisons use November 1, 2026 versus November 6, 2022, except Kansas: November 2 versus November 7. Party is registration in NC, KS and IA, modelled in TX and MI, and last-primary participation in OH.",
