Vice President JD Vance is encountering growing resistance from some of the Republican Party’s most influential pro-Israel voices following his central role in negotiating an end to the recent conflict with Iran. Yet despite criticism from conservative commentators and foreign policy hawks, many evangelical voters – one of the GOP’s most important electoral constituencies – remain open to supporting him as a future presidential candidate.
The divide became apparent during the Faith and Freedom Coalition’s annual Road to Majority Conference in Washington, where hundreds of conservative Christians gathered to celebrate President Donald Trump’s political agenda while discussing the future of the Republican Party after Trump’s presidency. Although many attendees praised Trump’s decision to launch military operations against Iran, they did not uniformly reject the administration’s subsequent diplomatic efforts led by Vance. Instead, interviews with conference participants suggested that the vice president continues to enjoy considerable goodwill among grassroots conservatives, even as prominent pro-Israel influencers question his foreign policy credentials.
Since helping broker an end to the Iran conflict, Vance has become the target of criticism from several high-profile conservative commentators known for their unwavering support of Israel. Some argue that the administration conceded too much during negotiations, while others have questioned whether Vance fully shares the traditional Republican commitment to Israel’s security.
Several influential conservative media personalities have instead promoted Secretary of State Marco Rubio as the stronger choice to lead the Republican Party after Trump leaves office. Their concerns reflect a broader debate inside the GOP over America’s role in the Middle East. While one faction continues to advocate an assertive foreign policy centered on unwavering support for Israel, another increasingly favors limiting U.S. military involvement overseas while relying more heavily on diplomacy.
Vance has become closely associated with the latter approach. Nevertheless, that distinction appears less important to many rank-and-file Republican voters than it is to Washington’s foreign policy establishment.
Support for Israel remained one of the strongest themes throughout the conference. Faith and Freedom Coalition chairman Ralph Reed received one of the loudest ovations after praising President Trump for what he described as showing both “courage and clarity” by authorizing military action against Iran.
Many attendees framed support for Israel not simply as a strategic alliance but as a religious obligation rooted in biblical teaching. Doug Thompson, a Kentucky pastor who attended the conference with his wife, said their long-standing commitment to Israel was shaped by both faith and personal experience, including a trip to Israel during their 50th wedding anniversary.
He expressed concern over rising antisemitism while arguing that the United States has a moral responsibility to stand alongside its Middle Eastern ally. Yet Thompson stopped short of criticizing Vance, saying he remained open to supporting several Republican contenders in 2028, including Vance, Rubio, Florida Governor Ron DeSantis and Texas Governor Greg Abbott.
For many conference attendees, Vance’s effectiveness inside the Trump administration outweighed disagreements over foreign policy. James Gallagher, a retired Marine from Maryland, praised the vice president’s record, noting that Vance has consistently delivered results whenever assigned major responsibilities by President Trump. Gallagher said Vance’s own military service and willingness to take on difficult negotiations had strengthened his credibility among conservative voters. Others echoed similar sentiments.
Kim Hunter of Pennsylvania argued that Vance has transformed what has traditionally been viewed as a ceremonial vice presidency into one of the administration’s most active positions. She dismissed criticism over his negotiations with Iran, saying the vice president had demonstrated leadership well beyond the expectations typically associated with the office. Younger Republicans also expressed confidence in Vance.
Grayson Hollifield, a first-time voter in the next presidential election, described the vice president as trustworthy and authentic, qualities that could resonate with Republican primary voters searching for the party’s next generation of leadership. Despite Vance’s support, Marco Rubio remains the preferred candidate for many conservative activists.
Several attendees cited Rubio’s extensive foreign policy experience and years of service on national security issues as significant advantages over the comparatively inexperienced vice president. Steven Patrick of Pennsylvania argued that Rubio possesses stronger leadership skills and broader international experience, making him the better candidate to guide the Republican Party after Trump. Some participants even envisioned a future ticket pairing Rubio with Pennsylvania Senator Dave McCormick, illustrating that the contest for the Republican nomination remains far from settled.
Even among those favorable toward Vance, Rubio frequently emerged as the first choice. Tessa Gallagher acknowledged Vance’s rapid political rise but suggested that his relatively short time in national office leaves questions about whether he is fully prepared for the presidency.
Still, she emphasized that she would enthusiastically support him if he ultimately became the Republican nominee.
The debate surrounding Vance reflects deeper questions about the future direction of Republican foreign policy. Recent polling indicates that Republican voters continue to approve of the Trump administration’s handling of the Iran conflict even as public support nationally has declined. At the same time, Americans increasingly express skepticism about extensive U.S. involvement in overseas conflicts and question whether Washington has become overly aligned with Israeli interests.
Vance’s efforts to negotiate an end to the war have therefore placed him at the center of competing expectations. To some conservatives, diplomacy represented pragmatic leadership that prevented a prolonged regional conflict. To others, any compromise with Iran raised doubts about America’s commitment to its closest Middle Eastern ally.
Joshua Botello of Utah reflected those concerns, saying he questioned whether Vance shared the same commitment to Israel held by many evangelical Christians. “I believe as Israel goes, so America goes,” he said, expressing a view widely shared within evangelical political circles.
Although the 2028 presidential race remains years away, discussions at the conference demonstrated that Republican voters are already beginning to evaluate potential successors to President Trump. Neither Vance nor Rubio attended the gathering, which instead focused primarily on celebrating the administration’s legislative accomplishments and maintaining Republican control of Congress.
Still, conversations throughout the event suggested that the contest to inherit Trump’s political coalition has quietly begun. While influential pro-Israel commentators continue attempting to weaken Vance’s standing among conservative voters, the conference revealed that many evangelicals remain unconvinced by those criticisms. For them, Vance’s record inside the administration, military background, and visible role in advancing Trump’s agenda continue to outweigh disagreements over his approach toward Iran.
Whether that support endures as the Republican primary approaches will likely depend on how the party ultimately defines its foreign policy priorities in the post-Trump era. For now, however, JD Vance remains firmly in the conversation as one of the leading contenders to carry the Republican banner into the next presidential election.
