Donald Trump says he'd be shocked if Taylor Swiftendorsed President Joe Biden again ... 'cause Donald says he made her a ton of money -- and implied he expects some loyalty.
The former prez took to Truth Social early Sunday morning and addressed the world's biggest celebrity couple -- as well as rumblings that Taylor would endorse Biden again.
DT started by touting one of his legislative accomplishments ... passing the Music Modernization Act -- a law that basically changed the way songwriters and music publishers are paid certain royalties -- on the whole, it helps artists receive fairer compensation.
The MMA was signed into law in 2018, under 45 ... so he feels he helped make Swift some serious cash -- adding Joe Biden hasn't done "anything for Taylor, and never will."
While not outright complimentary of Swift, this seems like a shift away from his campaign's reported strategy regarding the world's biggest pop star.
Remember ... Rolling Stone reported the Trump campaign was preparing for a "holy war" against her. Unclear exactly what that means, but this isn't the blatant condemnation one would expect from holy warriors.
