In redistricting some districts draw themselves. The population and geography just work out that way.
Consider the City of Sacramento. The incorporated area is 814 people more than the ideal population for an Assembly District.
This district would place two newly elected Members of the Assembly together in the same district. Assemblyman Richard Pan and Assemblyman Roger Dickinson both live in the incorporated city so one would have to move or they would have to run against each other in this Democrat controlled district.
The other thing that this would do is pack most of the solidly Democrat areas into one district. The other two districts that are likely to come from the remainder of Sacramento would at least be competitive for Republicans.
I plan on publishing a number of maps in the coming weeks but this is the first one.
