WASHINGTON -- Rep. Howard Berman (D-Calif) picked up some surprising supporters in his race against fellow Democratic Rep. Brad Sherman (Calif.): Republican senators.

Sens. John McCain (R-Ariz.) and Lindsey Graham (R-S.C.), along with Sen. Joe Lieberman (I-Conn.), announced their endorsements for Berman on Monday. Berman, the ranking member on the House Foreign Affairs Committee, is facing off with Sherman in November as a result of redistricting and California election laws that allow the top two vote-getters in a primary election to advance to the general election, regardless of their party.

McCain, Graham and Lieberman are all prominent voices on foreign policy, hence their support for Berman.

"Howard and I have worked on a bipartisan basis on issues ranging from human rights to missile defense," McCain said in a statement. "He's smart, tenacious, and someone who has a record of bipartisan accomplishment and effectiveness."

Graham said in a statement, "He works hard every day to advance America's agenda and has been instrumental in passing laws to prevent the spread of nuclear weapons, stop arms sales to nations that support terrorism, and keep our country safe. We need his effectiveness and bipartisan leadership in Congress."

"When Israel's leadership needs a friend in Congress, that ally is Howard Berman," Lieberman said in a statement.

A Sherman campaign spokesman did not immediately respond to a request for comment.

A July poll showed Sherman 27 points ahead of Berman. The internal poll for Sherman, conducted by the Feldman Group, showed that Sherman took 52 percent to 25 percent for Berman. Twenty-three percent were undecided.
