The process is as messy as democracy itself.
Some states try to remove politics from the redistricting equation.
Colorado, for instance, relies on a commission to draw the lines. Voters who have moved into or out of Colorado may or may not be able to tell the difference. Regarding redistricting, neither party occupies the high ground.
