As I mentioned earlier on the blog, GOP women are struggling to win in primaries this cycle, especially in places that will be competitive in November. According to the Center for American Women and Politics, Republican women are just 18 percent of their party's candidates in House races where filing deadlines have passed as of April 26, and just 14 percent of nominees as of May 8. By comparison, women are 36 percent of all Democratic candidates, and a whopping 41 percent of Democratic nominees thus far. One female Republican hopeful running today is Mariela Roca, in Maryland's 6th District. She is trailing (11 percent) with 30 percent of the expected vote reporting.

Former President Donald Trump, who endorsed Justice in October, celebrated the governor's victory on his social media account shortly after the race was called in West Virginia. "Congratulations to Big Jim Justice!" Trump wrote on Truth Social.

Justice, in his own post (on X), nodding to the former president's "America-First" agenda. "Thank you, West Virginia, for placing your support and trust in me. I am truly humbled and will work every day to win in November so we can flip the Senate and deliver on our America-First agenda!" Justice wrote.

The two have a short but storied history. Justice switched his party registration from Democratic to Republican in 2017, announcing the high-profile shift at a Trump rally in Huntington, West Virginia.

In Baltimore, Democratic voters are choosing between a current and former mayor, and the race looks very close. Former mayor Sheila Dixon is currently leading incumbent Brandon Scott by less than a tenth of a percentage point with mostly early vote reported, according to the state's board of elections.

This is Dixon's third attempt to return to the mayor's office since she resigned in 2010 after being found guilty of embezzlement. In 2016, she narrowly lost the primary to Catherine Pugh, who later went on to plead guilty to conspiracy and tax evasion. Then in 2020, Dixon lost the primary to Scott by just 2.1 percentage points, though a crowded field of 24 candidates meant neither put up a strong showing.

Perhaps ironically, Dixon's campaign this time around focused in part on crime, an issue that 79 percent of Baltimore voters cited as "extremely serious" or "very serious" in a March Washington Post/University of Maryland poll, far more than other areas of the state. Thirty-two percent of Baltimore City voters also told the pollsters that they feel "not too safe" or "not at all safe" from crime in their neighborhoods.

Two different surveys of the mayoral primary in April both showed a single-digit race with Scott ahead, so this one might go down to the wire.

As results start to stream in across the state, the map for the Democratic primary for Maryland Senate looks great for Trone. Unfortunately for him, the vote totals are showing a much closer race, with Alsobrooks currently ahead by around 3 points, thanks to a strong showing in Baltimore and a significant lead in her home county, Prince George’s County. As more votes are reported, we’ll be keeping an eye on whether Alsobrooks can maintain her small lead, and if it starts to be reflected geographically.

This week's primaries are ovah, so we're calling it a night! Here are the most important races where ABC News has reported a projection:

- Maryland's Senate matchup is set. In the GOP primary, former Gov. Larry Hogan easily dispatched his primary opposition, giving Republicans their best possible nominee for what will still be a very tough general election in deep-blue Maryland. In the Democratic primary, meanwhile, Prince George's County Executive Angela Alsobrooks edged out Rep. David Trone in an expensive, hard-fought race. She now has the chance to become just the third Black woman elected to the Senate in U.S. history.

- In Maryland's 3rd District, state Sen. Sarah Elfreth won the very crowded Democratic primary, defeating Harry Dunn, the former Capitol Hill police officer who helped defend the Capitol during the Jan. 6 insurrection. Given the district's blue lean, Elfreth should win in November, adding more women to the House, where women are still just 29 percent of its members.

- Attorney General Patrick Morrisey won the Republican primary for West Virginia governor in a close race over former state Del. Moore Capito. He's heavily favored to win in November in this red state and will likely be a hardline conservative governor, as he's associated with the tea party wing of the party.

- In the GOP primary for West Virginia senator, Gov. Jim Justice easily defeated Rep. Alex Mooney, carrying all but four counties in exurban Washington, D.C. Justice will be heavily favored to win the seat being vacated by Democratic Sen. Joe Manchin, who announced his retirement last year.

- In the Republican primary for West Virginia's 1st District, incumbent Rep. Carol Miller fended off a far-right challenge from former state Sen. Derrick Evans, who'd previously served three months in jail after being found guilty in a case related to the Jan. 6 insurrection. She'll be favored to comfortably hold on to her seat in November.

- In the Republican primary for West Virginia's 2nd District, state Treasurer Riley Moore romped to victory over several other GOP candidates vying to succeed Mooney (who ran for Senate). Moore is the nephew of Sen. Shelley Moore Capito and the grandson of former Gov. Arch Moore; he'll be a shoo-in this fall for the deeply Republican seat.

- In Maryland's 6th District, which was vacated by Trone for his ill-fated Senate bid, Democrats went with a familiar name in their primary: April McClain Delaney, a former Biden administration official whose husband, John Delaney, held this seat for six years before Trone. On the Republican side, voters once again expressed their support for Neil Parrott, a local lawmaker who was the GOP nominee in 2020 and 2022. Delaney will be favored in the general election, but this is a seat that could get competitive under the right circumstances for Republicans.

- In Maryland's 2nd District, Democratic voters nominated Baltimore County Executive John "Johnny O" Olszewski Jr. to face off against Republican political commentator and frequent political candidate Kimberly Klacik. Biden won general election voters in this district 59 to 39 percent in 2020, so it's highly likely Johnny O will be the next representative of this northern-Baltimore seat.

- In Nebraska's 2nd District, Rep. Don Bacon easily turned back a primary challenge from right-wing Republican Dan Frei. That's bad news for Democrats, who would've had a much easier time beating Frei than Bacon in November in this swing seat.
