Former President Donald Trump's campaign is closely monitoring Vice President Kamala Harris' running mate decision, according to sources close to Trump. While advisers believe the pick may not have a significant long-term impact on the race, they have been gathering opposition research on top contenders such as Pennsylvania Gov. Josh Shapiro and Minnesota Gov. Tim Walz.
Some Trump allies have expressed concerns about Shapiro potentially delivering Pennsylvania to the Democrats in November. However, a Trump adviser dismissed this concern, stating that Shapiro has not yet been fully vetted on a national stage.
Trump has been testing new attack lines on Harris, including questioning her ethnicity. The campaign plans to continue portraying her as a radical Democrat and linking her to President Joe Biden's policies, particularly on crime, immigration, and inflation.
