Four More Primaries Set For Tuesday

WASHINGTON (AP) — Voters across Maine, Nevada, South Carolina and North Dakota head to the polls for another day of primary elections in America. But much of the political world will be focused on Maine’s high-stakes U.S. Senate contest. The results are not in question. Neither Republican incumbent Sen. Susan Collins nor Democratic challenger Graham Platner faces serious opposition for their party’s nomination. But Tuesday still marks a big moment for Platner, the embattled veteran and oyster farmer, who’s fighting to rebuild his credibility in a campaign rocked by controversy. Elsewhere, President Donald Trump’s clout within his party will be tested in South Carolina and Nevada, where he’s endorsed his favored candidates.
