WASHINGTON (AP) — President Joe Biden and former President Donald Trump have clinched their parties’ presidential nominations with decisive victories in a slate of low-profile primaries, setting up a general election rematch that many voters do not want. The outcome of contests Tuesday in Georgia, Mississippi, Washington state and Hawaii was never in doubt. Neither Biden, a Democrat, nor Trump, a Republican, faced major opposition. But the magnitude of their wins gave each man the delegate majority he needed to claim his party’s nomination at the summertime national conventions. There is no longer any doubt that the fall election will feature a rematch between two flawed and unpopular presidents. It will almost certainly deepen the nation’s searing political and cultural divides.
