CBS News estimates Maryland Senate race leans Democrat

What's at stake in Senate elections
Control of the Senate is up for grabs as Democrats look to defend their narrow majority, facing serious headwinds with few pickup opportunities — and ample room for the GOP to grow.
Democrats currently have a 51-49 majority in the chamber. But Sen. Joe Manchin's decision to leave Congress all but guaranteed Republicans will flip his seat in deep-red West Virginia, and Republicans have opportunities in several other states that will determine control of the upper chamber.
Republicans last won a majority in the Senate in 2018, before Democrats went on to secure a narrow majority in the two most recent elections. And control of the upper chamber has major implications for the new administration — either bolstering the president's agenda, or serving as a blockade for the opposing party.
11 key Senate races to watch
One-third of the chamber is in play in the 2024 cycle. Some of those 34 seats are considered safe for one party or the other, but a number of races are highly competitive or likely to flip. Control of the Senate will come down to the outcomes in nearly a dozen races.

Sherrod Brown — the only Democrat holding statewide office in Ohio — is fighting to hold onto the seat he first won in 2006, as businessman Bernie Moreno, a Trump-backed Republican who has embraced election denialism, makes a play for the seat in what has been among the most expensive races this cycle.

In Michigan, former Republican Rep. Mike Rogers and Democratic Rep. Elissa Slotkin are vying for Sen. Debbie Stabenow's long-held seat in the upper chamber as Stabenow prepares to retire.

Maryland Senate race: Larry Hogan vs. Angela Alsobrooks
Prince George's County Executive Angela Alsobrooks, a Democrat, and former Maryland Gov. Larry Hogan, a Republican, are facing off in a race that's grown unexpectedly competitive in deep-blue Maryland, as the two look to replace Sen. Ben Cardin.

Nevada Senate race: Jacky Rosen vs. Sam Brown
Democratic Sen. Jacky Rosen is looking to hold onto her seat in her first reelection bid, facing off against Sam Brown, a businessman and former Army captain. Nevada was home to one of the closest Senate races in the country in 2022, and although Republicans haven't won a Senate race in the Silver State since 2012, they flipped the governor's mansion in the last election, suggesting that this seat could be in play for the GOP.

Texas Senate race: Ted Cruz vs. Colin Allred
Once considered a long-shot Democratic bid in the red state, Rep. Colin Allred has launched a formidable challenge against Sen. Ted Cruz, who has held the seat since 2013. No Democrat has won a statewide election in Texas since 1994, and the Cook Political Report rates the race as lean-Republican. But Texas remains among Democrats' best pickup opportunities in the upper chamber.

Arizona Senate race: Ruben Gallego vs. Kari Lake
Democratic Rep. Ruben Gallego and Republican Kari Lake are duking it out for the seat held by Sen. Kyrsten Sinema, a Democrat-turned-independent who isn't seeking reelection. The Cook Political Report rates the race as leaning toward Democrats, as Gallego, a progressive lawmaker and former Marine, has worked to court voters in the middle, and Lake, who lost a hard-right bid for governor in 2022, has tried to do the same.

Considered among the most endangered Democrats this cycle, Sen. Jon Tester is fighting to keep the Senate seat he's held for nearly two decades against a challenge from businessman and former Navy SEAL Tim Sheehy.
