How an AIPAC endorsement became a liability

AIPAC is spending big on Democratic primaries. It doesn’t always work out.

The American Israel Public Affairs Committee — better known by its short name, AIPAC — bills itself as a bipartisan advocate “for policies that strengthen the US-Israel partnership.” In 2026, it’s become something else: a major — and seemingly, losing — issue in Democratic politics.

Progressive Democratic candidates in primaries across the country are explicitly calling out their opponents’ relationship with AIPAC, often using the connection as a rallying point to persuade voters about the problem of “dark money” in politics. Most recently, in Michigan, AIPAC spent about $30 million boosting Rep. Haley Stevens in her bid for the state’s Democratic Senate nomination. Her opponent, Abdul El-Sayed, drew attention to it again and again. She lost.

The last time AIPAC went all-out to undermine a Michigan candidate

As one of the biggest spenders in US elections, the group has gone well beyond its origins lobbying members of Congress to support its agenda. According to David Dayen, executive editor of the American Prospect, AIPAC is spending millions of dollars against candidates who speak out against Israel’s actions in Palestine — sometimes using advertisements that have nothing to do with Israel, and may appear unrelated to AIPAC.

Dayen spoke with Today, Explained co-host Noel King about the backlash surrounding AIPAC’s spending, the group’s complicated web of shell PACs, and what it all means for the Democratic Party’s quickly evolving stance on Israel.

How Israel lost the Dems

Below is an excerpt of their conversation, edited for length and clarity. There’s much more in the full podcast, so listen to Today, Explained wherever you get podcasts, including Apple Podcasts, Pandora, and Spotify.

AIPAC started out as a lobbying organization. It was inaugurated in the 1950s. It has historically been seen as one of the more powerful lobbying organizations in Washington. And its goal is to strengthen and maintain the relationship between the US and Israel.

They have annual conventions where pretty much everybody across the political spectrum attends and gives speeches. But something changed about five years ago. AIPAC was not content to just lobby members of Congress. They wanted to influence who actually got to Washington. And they began to engage in the use of super PACs to run advertising and other forms of political engagement in campaigns, and particularly in primary campaigns that determine who actually gets to a general election.

Why did they want to influence who got to Washington? Maybe that sounds like an obvious question, but it wasn’t happening........
