Donald Trump campaigned in Mount Pocono, Pennsylvania, rating the US economy under his administration an "A-plus-plus-plus-plus-plus" despite polls showing high voter negativity and disapproval of his economic handling.Trump dismissed "affordability" as a "hoax" while blaming Democrats for high prices, drawing criticism from Senator Bernie Sanders and local residents over rising costs, with JD Vance scheduled to address these issues next week in Pennsylvania.Recent Democratic electoral victories in Miami and Georgia, including flipping a state House district Trump carried by double digits last year, underscored potential political costs of the economic dissatisfaction and Trump's stance on affordability.
