BALTIMORE (AP) -- Hillary Clinton won the Democratic presidential primary in Maryland on Tuesday, and Donald Trump won the state's Republican presidential primary.
Polls had shown the Democratic front-runner and top Republican contender leading in the state. Maryland is 28 percent black, and Clinton has been a heavy favorite among African-American voters elsewhere.
"She's a trailblazer," said Hannah Forney, a Democrat who voted for Clinton in Annapolis. "She's been in the process a long time. She knows the rules. I trust her. She's misunderstood, and she's the best person for the job."
Jane Raymond, a 57-year-old health care administrator, said she voted for Trump.
"I just see a lot of energy around him -- and his independence," Raymond said.
Meanwhile, a judge ordered four Baltimore precincts to stay open an hour late Tuesday because they were late in opening, delaying the release of results in Maryland's primary until 9 p.m.
Rep. Donna Edwards, who lost the Democratic nomination for the state's open U.S. Senate seat to Rep. Chris Van Hollen, filed a request with the Baltimore Circuit Court to keep polling places in the city open until 10 p.m. because of the morning delays. After a Tuesday evening hearing that was disrupted by a small fire at the courthouse complex, Judge Althea Handy ruled that only four polling places would be kept open late.
The heated Senate race to replace retiring Sen. Barbara Mikulski and presidential campaign helped prompt a record number of Maryland voters to cast early ballots during the eight-day early voting period that ended Thursday.
Republicans in the Senate primary are hoping Gov. Larry Hogan's popularity will help propel them to victory in November in a state where they are outnumbered by Democrats 2-1. Del. Kathy Szeliga, who represents parts of Baltimore and Harford counties, emerged the winner in a crowded GOP field.
In Baltimore, state Sen. Catherine Pugh defeated former Mayor Sheila Dixon in a crowded Democratic primary for mayor. She will face Republican Alan Walden in the general election but is widely expected to win in what has historically been a Democratic stronghold.
Pugh's campaign spokesman, Anthony McCarthy, said some people who showed up at one of her offices broke car windows and slashed tires when they were told they couldn't work at polling places. Pugh then decided anyone who showed up to work would be allowed to work and be paid for it, McCarthy said. One man was arrested after Baltimore police said he used a rock or a brick to break the window of a security vehicle.
Meanwhile, Mikulski's retirement is rippling into two congressional districts that include the suburbs of the nation's capital, seats now held by Van Hollen and Edwards.
In the 8th Congressional District seat held by Van Hollen, state Sen. Jamie Raskin, a constitutional law professor, won the Democratic primary. He defeated wine superstore owner David Trone, who broke the record for the amount a self-funded House candidate has ever put into a single campaign -- $12 million. Raskin also defeated former local television anchor Kathleen Matthews, who is married to MSNBC's "Hardball" host Chris Matthews. The crowded primary also included state legislators Kumar Barve and Ana Sol-Gutierrez.
In the neighboring 4th Congressional District, former Lt. Gov. Anthony Brown defeated former Prince George's County State's Attorney Glenn Ivey and Del. Joseline Pena-Melnyk in the Democratic primary for the seat Edwards has held since 2008.
