Redistricting California (Part 2): State Senate

(More great stuff on redistricting California from cali_girl_in_texas – promoted by Brian Leubitz)

Here is my attempt at redistricting the California State Senate. With over 936,000 people per district, satisfying communities of interest becomes a bit more challenging. Here are the districts I ended up drawing.

Majority-White: 22

Majority-Hispanic: 8

Majority-Minority: 10

Safe Dem: 19

Likely Dem: 1

Lean Dem: 3

Toss-Up: 7

Lean GOP: 3

Likely GOP: 6

Safe GOP: 1

EDIT BY BRIAN: See the flip for the full run-down of the Senate districts in this proposed map.
