The Supreme Court today denied an appeal of California’s redrawn map of congressional seats.

The change in district lines will make it difficult for Rep. David Valadao, a Republican member of the House Agriculture Appropriations Subcommittee, and for the successor to the late Rep. Doug LaMalfa, a Republican member of the House Agriculture Committee, to win election in the future.

California voters approved a remap organized by Gov. Gavin Newsom, a Democrat, after President Trump urged Texas to redraw its maps in favor of Republicans, and Texas redrew its map.

Newsom has set August 4 for a special election for voters to choose a successor to LaMalfa in his current district, but the winner of that election will be in office only for the remainder of this congressional session. In the November general election, candidates will have to run in the newly redrawn district that favors Democrats.

On Monday, Maryland’s House of Delegates passed a new Democratic gerrymander, Sabato’s Crystal Ball at the University of Virginia Center for Politics reported.

“The plan appears to face significant opposition in the state Senate and, even if it passed there, could be struck down by state courts,” the article said.

But if the new map goes into force, it would endanger the re-election chances for Rep. Andy Harris, R-Md., the House Agriculture Appropriations Subcommittee chairman who also heads the Freedom Caucus.
