US and Europe’s right-wing power tests: Vance’s fading successor odds and Le Pen’s Ukraine funding reality check

On September 6, 2026, multiple outlets highlighted political inflection points that could reshape policy trajectories in the US and Europe. In Russia’s kommersant, the narrative is that Vice President JD Vance is losing ground in the internal struggle over who could succeed Donald Trump, with his position described as less stable than it was late last year. Separately, CNN-linked reporting framed the 2026 US midterm elections as the biggest test yet for Turning Point, focusing on the organization’s question of what it becomes “without Charlie Kirk.” In France, bignewsnetwork quoted Marine Le Pen’s party leadership arguing that France cannot finance Ukraine forever, while NZZ reported that Le Pen’s key economic adviser, François Durvye, has left after an intrigue, prompting a shift back toward older social-policy themes in her campaign. Geopolitically, these stories converge on a common theme: domestic political constraints are increasingly likely to condition external commitments. In the US, uncertainty about succession dynamics around Trump and Vance matters because it can affect how reliably Washington sustains pressure on Russia, supports Ukraine, and manages allied burden-sharing—especially around the 2026 midterms when political capital is scarce. The Turning Point question signals whether a major right-wing mobilization engine can maintain influence without a central figure, which could alter the intensity and framing of debates on foreign aid and immigration. In France, Le Pen’s “can’t finance Ukraine forever” line is a direct attempt to redefine the cost-benefit calculus of European support, while the adviser departure suggests internal contestation over economic strategy and how it should align with a harder or softer posture toward social spending. Market and economic implications follow the political fault lines. A credible shift toward reduced or conditional Ukraine financing would likely raise risk premia for European defense and reconstruction-linked supply chains, while also feeding volatility in European sovereign spreads and defense contractor equities; the direction is toward higher uncertainty rather than immediate policy implementation. In FX terms, the political narrative can pressure EUR sentiment if investors price in weaker fiscal capacity or more fragmented EU coordination, while USD may remain supported if US domestic politics increases the probability of policy discontinuity. Sectorally, attention should focus on defense procurement, energy security, and logistics insurance tied to Eastern European corridors, because these are the areas most sensitive to changes in political willingness to sustain funding. Even without explicit sanctions or new legislation in the articles, the signaling effect can move expectations for budgets, contracts, and aid disbursement schedules. What to watch next is whether these political narratives translate into concrete legislative or budgetary actions. For the US, track 2026 midterm campaign messaging on foreign aid, the composition of right-wing advocacy coalitions after the Turning Point leadership question, and any public positioning by JD Vance relative to Trump on succession and Ukraine policy. For France, monitor Le Pen’s platform details after Durvye’s exit, especially any quantified proposals on social spending versus defense and Ukraine-related commitments, and whether party rhetoric softens or hardens as election timelines approach. Trigger points include committee hearings, budget amendments, and coalition negotiations that explicitly reference Ukraine funding levels. If rhetoric escalates while fiscal constraints tighten, the probability of policy retrenchment rises; if parties converge on compromise language, the risk of abrupt funding cuts declines.
