How to read Senate cards

The line is raw polling D−R. PVI is a long-run baseline, not current support. The rating is a consensus category—not a probability—and the House transfer model is not applied to Senate races.

解释边界

本页不输出胜率、席位数或因果判断。参院折线是原始民调,不等于评级;PVI 是结构底色,不等于当前支持率;众院边际是 provisional 全国传导估计;评级不转换为概率。
