IN THE FINAL DAYS leading up to Maryland’s Democratic voters going to the polls on Tuesday to choose their U.S. Senate nominee, Rep. Donna Edwards has been barraged by ads and mailers from the Super PAC backing her opponent, Rep. Chris Van Hollen, called the Committee for Maryland’s Progress.

A television ad assails Edwards as “one of the least effective members of Congress,” contrasting her career with Van Hollen’s legislative record. It mentions no foreign policy issues, despite the dominant issue motivating one of the Super PAC’s largest funders.

Recently released disclosures reveal that $100,000 — a sixth of what the Super PAC has raised —comes from a single source: a donation by pro-Israel billionaire Haim Saban.

A “One-Issue Guy”

Saban, who made his fortune in the media and entertainment industry, has spent millions of dollars influencing the foreign policy establishment, including by sponsoring the Brookings Institution’s Saban Center for Middle East Policy and funding the American Israel Public Affairs Committee (AIPAC). He is also one of the largest donors to Hillary Clinton’s Super PACs. In a 2010 interview with the New Yorker, he described himself as a “one-issue guy, and my issue is Israel.”

Last year, he briefly teamed up with GOP megadonor Sheldon Adelson to sponsor an effort to counter university boycotts and divestment from Israel’s occupation. “When it comes to Israel, we are absolutely on the same page,” he said of Adelson. “When it comes to this, there is no light between us at all.”

Following the Paris terrorist attacks, Saban called for “more scrutiny” of Muslims. “You want to be free and dead? I’d rather be not free and alive. The reality is that certain things that are unacceptable in times of peace — such as profiling, listening in on anyone and everybody who looks suspicious, or interviewing Muslims in a more intense way than interviewing Christian refugees — is all acceptable [during war],” he told The Wrap. “Why? Because we value life more than our civil liberties and it’s temporary until the problem goes away.”

Days later, he walked back his remarks, saying he “misspoke” and that all “refugees coming from Syria” should “require additional scrutiny,” regardless of religion.

A Maryland Divide Over Israel and the Palestinians

Last week, Sheryl Gay Stolberg of the New York Times wrote that the Maryland Senate race involves “slight differences in policy.” But on Israel and the Palestinians, Edwards has significantly departed from the status quo in votes and statements in ways that her opponent has not.

During “Operation Cast Lead,” the sustained bombing campaign of Gaza that began in late 2008 and lasted through the middle of January 2009, 390 members of Congress, including Van Hollen, voted in favor of a one-sided resolution affirming support for Israel’s conduct during the war; Edwards voted “present.”

In November of 2009, the House of Representatives voted 344 to 36 to call on the administration to oppose endorsement of the United Nations’ “Goldstone Report,” which described war crimes by both Israel and Hamas during the previous year’s war. Van Hollen voted with the majority, and Edwards was one of the few who voted no.

Following the 2010 deaths of activists aboard a Gaza-bound flotilla carrying humanitarian aid to the territory under Israeli blockade, Israeli officials and right-wing supporters of the government there denied that there was a growing humanitarian crisis in the territory.

“I think all international institutions have acknowledged a humanitarian crisis in Gaza,” Edwards told me at the time. “I have long said that I don’t think the blockade is really sustainable for the people of Gaza.” Van Hollen’s statement on the event — highlighted on AIPAC’s website — was more muted; it did not condemn the embargo but affirmed that the “U.S. must also continue to make sure humanitarian assistance is able to reach the people of Gaza.”

In November 2015, all but one member of the Maryland congressional delegation signed onto a House letter written to Palestinian Authority President Mahmoud Abbas condemning the “recent wave of Palestinian violence in Israel and the West Bank.” By mid-October seven Israelis had been killed in stabbings and similar incidents, and dozens had been wounded. In the same time frame, almost 30 Palestinians had been killed by Israeli military attacks and nearly 2,000 had been injured.

Van Hollen signed the letter, Edwards did not. Asked by Washington Jewish Week why she did not sign the letter, she gave a brief statement condemning the violence as a whole, not just one side’s attacks:

I condemn the violence affecting the lives of Israelis and Palestinians, and urge both sides to return to the negotiating table to seek peace. It is critical that we ensure the State of Israel as a secure Jewish democratic state by making a two-state solution a reality, with the recognition of an independent Palestinian state that respects and recognizes the State of Israel.

“If you take their records side by side, she’s in the bottom 5 percent of the class and he’s up there, among the top,” Morris J. Amitay, a former AIPAC executive director, said in comments to the Baltimore Sun. “I’ve never seen such a disparity.”
