Republican Senator J.D. Vance's nomination as former President Trump's running mate has stirred unease among GOP lobbyists and foreign policy experts due to his departure from party norms on issues like Ukraine, corporate regulation, and the 2020 election results. Vance's alignment with Trump's stance on the election and his controversial remarks have raised concerns about his suitability as a vice president. Despite his appeal to blue-collar workers and younger Republicans, Vance faces criticism for his shifting policies and potential alienation of moderate voters. His selection reflects a strategy to secure support in swing states and appeal to Trump's base, emphasizing commonalities in their views on various issues. While some praise Vance's ability to connect with working-class voters, others highlight his vulnerabilities and past criticisms of Trump.
