President Biden and former President Trump won the Louisiana primary on Saturday, amassing more delegates after already clinching their parties' nominations.
Biden also appeared in the Democratic primary in Missouri. The results are not expected to be announced before next week.
Biden and Trump have already beaten their main rivals. But primary races are still being closely watched by those familiar with turnout and signs of protest voters.
In the case of Biden, some progressives are casting protest votes to register their anger at his handling of the war between Israel and Hamas. It has been reported that more than 30,000 Palestinians, two-thirds of whom are women and children, have been killed by Gaza authorities since Israel launched its attack. The protest movement carried out by Arab-American communities in Michigan spread to several other states.
Trump succeeded in securing the nomination for the Republican Party for the third time in a row. But he faces opposition from people concerned about the massive legal jeopardy he faces and those critical of his tenure in the White House, which ended shortly after the deadly Jan. 6 insurrection launched by his supporters and stoked by his false claims of election fraud.
Saturday's primary was the first Democratic-run presidential contest in Missouri since a new law took effect in August 2022. Meanwhile, Louisiana's primary comes nearly four years after the state postponed its primary due to the pandemic. Covid-19.
