As Texas moves forward with an off-cycle redistricting to shore up Republicans’ narrow House majority, Gov. Gavin Newsom is plotting a Democratic response in California. But the state’s independent redistricting commission is a major obstacle.

Redistricting usually happens after the census count or in response to a court ruling. Texas' gerrymandering move and similar ones considered in other states may have far-reaching effects.

Gov. Gavin Newsom says California should redraw its own congressional districts if Texas tries to gerrymander its lines. His idea faces long odds.
