JD Vance, a senator from Ohio and Donald Trump's vice-presidential candidate, has taken an increasingly aggressive stance in his speeches, focusing on issues central to the Republican base, such as immigration and "pro-family" policies.

Vance has emphasized the issue of immigration, one of the main themes of Trump's campaign. During recent interviews on major television networks, he reinforced Trump's proposal for mass deportation of immigrants, suggesting that such a measure could begin with the deportation of a million immigrants, especially those involved in criminal activity. Vance criticizes Vice President Kamala Harris and the Biden administration, blaming them for the increase in migrant crossings across the U.S. southern border and argues that mass deportation, while challenging, should be addressed in a "sequential" way, starting with the most feasible deportations. Vance's rhetoric reflects Trump's stance, which has also previously hinted at using the National Guard to implement these large-scale deportations.

In addition to the topic of immigration, Vance has also been the target of criticism for comments he has previously made about "pro-family" policies. He was criticized for suggesting during a 2021 interview that childless Americans, including prominent Democratic Party figures like Kamala Harris, were less qualified to make policy decisions, referring to these people as "childless cat ladies." In another speech, Vance suggested that parents of children should have more voting power, an idea he described as a "thought experiment" rather than a concrete policy proposal, according to the same publication.

In recent interviews, Vance has tried to tone down the controversy surrounding his comments, stating that his words were distorted by the media and the Harris campaign. He reiterated that his goal is to promote policies that favor families, especially at a time when many Americans face economic hardship, such as rising living costs and medical expenses. Vance expressed regret for making statements that were misinterpreted but kept his focus on policies that he believes are more "pro-family."

Vance's role in Trump's campaign is described as that of an "attack dog," focused on criticizing Harris and the Biden administration, especially on sensitive issues such as immigration. His rhetoric and stance reflect the Republican campaign's strategy of mobilizing the conservative base around issues such as border security and support for families, while seeking to undermine Harris's popularity in swing states such as Pennsylvania, where she has a slight lead according to some polls.
