The national redistricting battle enters its next phase Thursday as California Democrats are scheduled to pass a new congressional map that creates five winnable seats for their party, a direct counter to the Texas House's approval of a new map to create more conservative-leaning seats in that state.

California Democrats are taking up their proposed constitutional amendment to temporarily redraw their congressional maps, hours after Republicans in the Texas House passed new maps of their own.

The Texas House of Representatives gave final passage on Wednesday to House Bill 4, a controversial Republican-backed proposal to redraw the state's congressional maps and potentially add up to five new GOP-leaning districts.
