U.S. voters across the political spectrum have developed a more unfavorable view of Israel, a trend CNN’s chief data analyst Harry Enten described as a "mammoth" shift. This significant change in public opinion, confirmed by multiple recent polls, could present challenges for the Republican Party in the upcoming general election.

"These are some absolutely huge, mammoth changes, generational changes that we’re talking about," Enten said Friday on CNN’s “News Central.” He noted that while some Republicans may anticipate using criticism of Israel against Democrats, public sentiment has evolved beyond partisan lines.

Israel's net favorability among Americans has been consistently negative since the spring, according to Enten's analysis. A Pew Research Center survey from March indicated that 60% of U.S. adults held an unfavorable view of Israel, an increase from 53% in 2025. A Marquette University Law School poll in April registered Israel's net favorability at minus 21 points.

Further data from an Ipsos poll conducted in April showed 39% of respondents had a favorable view of Israel, while 49% had an unfavorable view, resulting in a net favorability rating of minus 10 points. Gallup polls earlier this year also showed negative sentiment.

"We’re not just talking about the Democratic base anymore. We’re talking about the general electorate, as well. The general electorate has turned against Israel," Enten stated. "This is not just a left issue. It is an American issue when it comes to opinions on Israel."

A Washington Post-Ipsos survey from July 8 to July 13 revealed that 55% of 2,648 polled U.S. adults believe military aid to Israel should be reduced or entirely ended.

Enten highlighted the dramatic nature of this shift by comparing current data to the U.S. administration during President Donald Trump's first term. At that time, Israel's net favorability averaged plus 51 points, according to Enten's aggregate of several polls. The current average stands at minus 16 points, representing a 67-point decline in eight years. He concluded, "Israel used to be a consensus issue in American politics, and that was a pro-Israel position. Now the consensus has actually shifted, and now when it comes to the general electorate, it is a minus."
