Palin is viewed favorably by 89% of western Republicans, 86% in the northeast, 76% in the south, and 71% in the midwest.
An ideological caveat.
When you look at the ideological composition of Republican voters by region though it's less startling: 74% of Republicans voters in the NE describe themselves as conservatives, not all that different from the 75% in the midwest, 79% in the south, and 73% in the west.
