Hoyer endorses Rep. Berman over Rep. Sherman

"Howard Berman is a highly-respected leader sought after by his colleagues from both parties for his expertise in both domestic and foreign policy, and world affairs,” Hoyer said in a statement posted on the Berman campaign's Facebook page. “Howard Berman is respected by both Republicans and Democrats because of his approach as a legislator and decency as an individual. It would be a great loss to the country if Howard Berman did not return to serve in the Congress of the United States."

The two lawmakers were thrown into the same district by California's redistricting process. And the state's new primary system puts the top two vote-getters — regardless of party — in the general election. Most of the district is Sherman's old territory.

The race has caused many Democratic legislators to pick sides.
