Yes. The Democrats keep losing counties and gaining voters.
This is also happening at the state level, and is causing the Senate to become ridiculously radical. It only takes the support of 5.1% of US voters to filibuster a bill, and 12% to defeat a filibuster:
The "supervoters" making up that 5.1% and 12% are mostly in Republican states, and this has led to the Republican party drifting farther and farther right of the mainstream over time. For example:
"County" by itself means very little when it comes to population. There are more people living in Los Angeles County alone than there are in some entire states.
They address this and find the same gap in the normalized subset of rural vs metropolitan areas. The gap goes from 5 point to 66, which is slightly less.
democrat
143 counties, n=91 809 974
to
156 counties, n=133 796 619
And republican
292 counties, n=61 407 202
to
280 counties, n=46 244 883
So overall health is improving, but it is improving more when increasing sample size. It is normalized, but still different things are compared.
Thanks I didn't know all that about democrats and counties, seems more involved then I thought.
