WASHINGTON AP – The Supreme Court on Friday threw out electoral maps drawn by federal judges in Texas that favored minorities. The decision ultimately could affect control of the U.S. House of Representatives and leaves the fate of Texas’ April primaries unclear.

The justices ordered the three-judge court in San Antonio to come up with new plans that pay more attention to maps created by Texas’ Republican-dominated state Legislature. All four of the state’s new congressional seats could swing based on the outcome.
