Israel Lobby

Why were three of the most expensive congressional primaries in recent years all connected to criticism of the U.S.-Israel policy?

Its supporters and affiliated organizations contribute to candidates in both major political parties, including congressional leaders, presidents, and presidential candidates. According to campaign finance data, pro-Israel groups were among the largest political spenders during the 2024 election cycle.

One of the most prominent organizations within the lobby is the American Israel Public Affairs Committee (AIPAC). In 2024, AIPAC announced plans to spend $100 million targeting five congressional races involving candidates it viewed as unfriendly to Israel.[1]

The influence of the Israel Lobby is perhaps most visible in congressional primaries. The average House primary costs roughly $100,000–$500,000,[5] yet three of the most expensive congressional primaries in recent years all involved candidates, despite their ideological differences, who challenged key aspects of the U.S.-Israel policy.

  • Kentucky 4th Republican Primary (2026): Thomas Massie vs. Ed Gallrein — approximately $32–35 million spent.[2]
  • New York 16th Democratic Primary (2024): Jamaal Bowman vs. George Latimer — approximately $23–25 million spent.
  • Missouri 1st Democratic Primary (2024): Cori Bush vs. Wesley Bell — approximately $17–20 million spent.

In Thomas Massie’s case, he became the target of extraordinary outside spending for major disputes centered on the following:

  • He opposed U.S. foreign aid, including aid to Israel.
  • He opposed several pro-Israel resolutions following October 7.
  • He openly criticized AIPAC and the broader Israel Lobby.
  • He questioned U.S. involvement in Middle Eastern conflicts, including Iran.

People standing in line as they wait to vote.One of Thomas Massie’s criticisms of AIPAC was shared during an interview with Tucker Carlson. Massie stated that, at least among Republican members of Congress, many lawmakers have what he described as an AIPAC “babysitter” who maintains direct contact with the member and often has their personal cellphone number.[3]

The significance of these races extends beyond the individual candidates involved. Political organizations influence elections on many issues. What makes these cases noteworthy is not simply the amount of money spent, but the fact that all three involved candidates publicly challenged important aspects of U.S.-Israel policy and became targets of extraordinary outside spending. Whether one views that spending as legitimate political participation or undue influence, the message to other elected officials is difficult to miss.

These facts help explain why criticism of Israeli policy remains relatively rare in Washington despite growing public debate elsewhere. Members of Congress do not need to be explicitly told how to vote when they can observe the political consequences faced by colleagues who challenge influential pro-Israel organizations. The ability to mobilize tens of millions of dollars against individual lawmakers creates a powerful incentive to remain silent, avoid controversy, or fall in line.
