Backing Israel-Iran War, Democratic Senator Fetterman Makes Video Appearance at Republican Midterm Convention

Pennsylvania Democratic U.S. Senator John Fetterman appeared via video on September 10 on the first day of the Republican Party's first midterm convention held in Dallas, Texas, introducing his Republican colleague, Pennsylvania Senator Dave McCormick, to delegates attending the conservative gathering. According to Al Jazeera, the 57-year-old first-term senator described himself in the video as a "commonsense Democrat," but the very fact of his appearance at a Republican rally with Trump as its political center reflects a force reshaping American politics — open support for Israel, and policy consensus on the U.S.-Israeli joint war against Iran, has become an adhesive that cuts across party lines.

Fetterman has long been regarded as an outlier within the Democratic Party. Al Jazeera reported that he holds a clear-cut stance on Israel and openly supports the U.S. war against Iran, in sharp contrast to the position of his party's voters and progressives who criticize the aforementioned U.S. foreign policy. Fetterman said in the video: "I will always stand with America, and will always reject extremism and socialism and that anti-American way of life." In a recent interview with Fox News he also said: "I will not become a Republican, but I will be a Democrat willing to engage with anyone who is serious about talking." Rather than quelling questions about his party loyalty, the remarks have instead allowed the matter to fester further.

A joint poll released last month by The New York Times, Siena College and The Philadelphia Inquirer quantifies this cross-party realignment in stark terms: 73% of Pennsylvania Republicans approve of Fetterman's job performance, a sharp jump from 25% in 2024; at the same time, his approval rating among voters of his own party has plunged from 74% to 22%, and 63% of Democratic respondents view him unfavorably. In other words, in this Democratic senator's political career, his voter base has in effect undergone a left-right swap — and the policy issue driving the swap is precisely war and military intervention in the distant Middle East.

Brandon Boyle, a Democratic U.S. Representative from Pennsylvania, wrote on social media after Fetterman's video was broadcast: "A year ago I called John Fetterman 'Trump's favorite Democrat,' and tonight he proved it again." Al Jazeera reported that Fetterman is also facing questions about his ability to perform his duties. A recent Wall Street Journal article disclosed that he has canceled a series of meetings with constituents, including a June meeting with wounded veterans he skipped citing "feeling unwell," but then appeared on a Fox News program to discuss Israel and the U.S.-Israeli joint war against Iran. The trade-off between exposure on war issues and routine duties is thought-provoking.

Republicans are trying to use this midterm convention to inject momentum into the November 3 election. Al Jazeera analysis noted that Republicans currently hold only narrow majorities in both chambers, but the race remains in flux due to cost-of-living pressures and a decline in Trump's personal approval ratings; because only one-third of Senate seats are up for election this year, it is especially difficult for Democrats to recapture the Senate. Fetterman himself is not up for election this year; his term runs through 2028. Speculation about his party affiliation will not dissipate with a single video appearance — at a moment when American politics is being profoundly reshaped by foreign war issues, whether this cross-party policy alignment will continue to deepen or be torn open again in the next election remains an open question.
