The Latest: Maine primary election tests Platner’s support following mounting scandals

Voters across Maine, Nevada, South Carolina and North Dakota will cast their ballots Tuesday in 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 aren’t in question. Neither Republican incumbent Sen. Susan Collins nor Democratic challenger Graham Platner faces serious opposition for their party’s nomination. And yet Tuesday marks an especially significant 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 anew in states like South Carolina and Nevada, where he’s endorsed his favored candidates. Democrats hope to build momentum in Nevada in their broader push to reclaim key governor’s seats.

Here’s the latest:

4 Democrats running for crucial Maine congressional seat

Many Maine Democrats are voting to pick a candidate for the 2nd District, which Republicans see as a key chance to pick up a seat in the narrowly divided chamber.

Incumbent Rep. Jared Golden, a Democrat, is not seeking reelection. The 2nd District includes much of rural Maine and Trump has had great success there at the top of the ticket in the last three presidential elections.

The Republicans’ presumptive nominee is former Gov. Paul LePage. Democrats will choose between former Maine Secretary of State Matt Dunlap; state Sen. Joe Baldacci; former U.S. Senate candidate Jordan Wood; and social worker Paige Loud.

Nevada website shows the status of mail ballots

The Nevada Secretary of State’s Office has launched a website designed to provide transparency around mail ballots.

The website shows how many were mailed, returned and accepted. It also notes the number requiring fixes by voters. Nevada mails a ballot to every registered voter unless a voter opts out.

It’s one of several swing states where Trump disputed his loss in 2020 with false claims of fraud. The secretary of state at the time, a Republican, investigated various claims and found no evidence of any widespread fraud. Trump also has repeatedly attacked the use of mail ballots generally.

Secretary of State Cisco Aguilar, a Democrat, said he created the website to increase transparency around Nevada’s elections and provide a way for voters to see in real-time how many ballots are outstanding.
