Here it is by county in 2004
Yup. Never give up territory. I live in Michigan where less than 10 of our 83 counties consistently vote democrat and most of those are college towns. You also need to take into account things of strategic value. Again I can think of several reasons you folks wouldn’t want to lose Michigan with the world’s purist copper and an ocean of natural gas underfoot.
Texas obviously has oil, range and farmland among other things.
We need to be a nation but we need to be free to do it.
