WASHINGTON (AP) — President Joe Biden and former President Donald Trump won Louisiana’s primary on Saturday, collecting more delegates after they already clinched their party nominations. Biden also appeared in Missouri’s Democratic primary, which was not expected to report results until next week. The primary races Saturday were not in doubt. But they are still closely watched by insiders for turnout and signs of protest voters. For Biden, some liberals are registering their anger with Israel’s war against Hamas following the militant group’s Oct. 7 attack. Trump faces dissent from people worried about the immense legal jeopardy he faces or critical of his White House term.
