Former Congressman Darrell Issa is in a close race with Ammar Campa-Najjar, the grandson of a Palestinian terrorist responsible for the massacre of Israeli athletes at the 1972 Olympic Games in Munich, a new poll suggests.

San Diego Union-Tribune/10 News poll showed Issa barely leading Campa-Najjar, 46 to 45 percent, in California’s 50th district, a traditional Republican stronghold. The poll surveyed 508 likely voters with a margin of error of 5.4 percent.

The race is Campa-Najjar’s second race. In 2018, he nearly unseated then-Rep. Duncan Hunter Jr., who was under federal indictment for corruption. But he struggled to deal with revelations about his family’s connection to Palestinian terrorism.

As Breitbart News noted at the time:

Campa-Najjar’s father, Yasser Najjar, worked as a Palestinian official for decades.

The Union-Tribune describes Campa-Najjar as a “business owner and San Diego State University lecturer.” He worked locally for the Obama campaign and later for the Obama administration in Washington, DC. He is a Christian, contrary to rumors that spread in 2018.

Issa was a veteran congressman from the 49th district who retired before the 2018 elections, as his coastal district shifted markedly to the left; his former seat is now occupied by Rep. Mike Levin (D-CA), a left-wing Democrat.

The new poll also suggested falling support for President Donald Trump in the district.

Campa-Najjar has raised over $3 million for the race, while Issa has raised close to $5 million, according to the FEC.
