Republican presidential nominee Donald Trump and his running mate JD Vance have criticized Taylor Swift for endorsing Kamala Harris, with Vance calling her a 'disconnected billionaire celebrity' and Trump warning of backlash in the music industry. Vance's comments have drawn ire from Swift's fans, who noted the irony given Trump's own status as a billionaire. Swift's endorsement has reportedly spurred nearly 340,000 new voter registrations, highlighting her influence particularly among women voters. NBC correspondent Ali Vitali emphasized the significant impact Swift can have on mobilizing voters, countering Republican dismissals of her endorsement. Vance's remarks come amid ongoing controversies, including his previous comments regarding Haitian immigrants, which have further complicated his position in the campaign. The situation reflects a broader challenge for Republicans in responding effectively to Swift's considerable cultural clout.
