Under the "You Can't Make This Shtuff Up" category, the Democrats from Texas, to avoid a redistricting vote, have chosen to seek safe haven in Illinois, perhaps the poster child of gerrymandered districts to arrive at a predetermined outcome . . .
The truth about gerrymandering? The only time either party has a problem with it is when they aren't the party drawing the lines. The current effort in Texas actually eliminates much of the current gerrymandering that was undertaken to ensure that Democrats didn't have to compete for the seats. The current Texas map is filled with numerous "coalition districts", which is code for an intentionally gerrymandered district to ensure that a specific racial or ethnic group, or a combination of them, hold a majority of the eligible voters in that district. The map under consideration right now eliminates "coalition districts", and that's the problem that Democrats have with the effort.
Rural and urban areas have different interests, different needs. Placing all of Park and all of Jefferson County together in one district is going to be misrepresentative of the needs of Park, and rural Jefferson, County because the Denver Metro population centers that lie in Jefferson County are going to silence the voice of Park, and rural Jefferson, County. And while I would generally agree with you that districting should mostly honor county lines, I also see the benefit of parsing out rural Jefferson County from Urban Jefferson County because a single representative can't properly represent the interests of both segments of the county's population due to their completely divergent character.
