The incumbent US President Joe Biden will win the Arizona, Illinois, Kansas, and Ohio primaries, according to a forecast published in the Politico newspaper.
Earlier, Biden received the support of a sufficient number of delegates to the Democratic Party's national convention, where he will nominate a candidate for the US presidency. Biden currently has more than 2,300 delegate votes. To run for president, a candidate must receive the support of at least 1,968 delegates. His main rival, Donald Trump, also won the necessary number of delegate votes to win the Republican presidential nomination. His elections will take place on November 5.
