California was undergoing non-partisan redistricting, which when they started, republicans actually picked up a seat or two. See
https://gerrymander.princeton.edu/redistricting-report-card/New York actually is less gerry mandered than CA, neither CA nor NY list any party getting more representation than their votes. Illinois, however, is just as gerrymandered as Texas.
States where Democrats have the strong advantage due to gerry mandering:
* Illinois
* Oregon
* Nevada
* New Mexico
NY and CA are both states where representation roughly corresponds to votes. Democrats also have less strong advantages in Pennsylvania, Alabama, and Mississippi (out of all places!). I'm guessing Alabama and Mississippi are just flukes.
States were Republicans have a strong advantage due to gerrymandering:
* Utah
* Kansas
* Texas
* Louisiana
* Wisconsin (??)
* Ohio
* Kentucky
* North Carolina
* South Carolina
* Georgia
* Florida
Arkansas and Oklahoma are moderately biased to Republican. Republicans have minor advantages in Maryland, New Hampshire, and Iowa.
Given that representation is roughly balanced in NY and CA right now, the Democrats could probably get a bunch of seats out of those two states if they decide to gerrymander.
