Texas
Incumbent Senator Ted Cruz ran for re-election to a third term. At first, Cruz was considered incredibly vulnerable, largely due to a primary challenge from former Congressman Will Hurd. After a narrow victory in the primary, Cruz faced Collin Allred, the Democratic nominee in the general election. Cruz narrowly won, underperforming Presidential candidate Donald Trump in the general election.

Republican Primary
On June 4th, 2023, Ted Cruz filed the paperwork to run in the Republican Primary in the 2024 Republican primary election. Cruz, who had also previously ran for President in 2016, was an early front-runner, however his campaign failed to gain traction, and following former President Donald Trump's candidacy, Cruz withdrew from the race. Cruz stated that despite withdrawing from the Presidential campaign, he would continue to not seek re-election in the Senate. The next day, former congressman Will Hurd announced he will run in the Republican primary to replace Cruz. former State senator Don Huffines announced he will run a week later. Former congresswoman Mayra Flores also announced her campaign a month later. The primary was deemed competitive, with most polls showing Flores and Hurd heading to a runoff. However, on the last day to file to run, Ted Cruz announced his re-election campaign. The same day, Hurd and Huffines announced in a press conference that they will not drop out of the race. Flores considered withdrawing to run again in congress, however she never switched campaigns and instead remained in the campaign for senate. Despite being the incumbent, Cruz had a tough time being re-elected, as Hurd appealed to many suburban voters unpleased with the polarizing Cruz. As such, the two became the quick frontrunners and most polls showed Cruz with a small lead over Hurd, not enough to avoid a runoff. In May 7th 2024, during the Republican primary, Hurd narrowly got more votes than Cruz and the two went into a runoff. Huffines endorsed Cruz in his concession speech whilst Flores declined to endorse any candidate, although pledging to support the nominee in the general election. In the June 5th runoff, Cruz narrowly won over Hurd Nominee Eliminated in runoff Eliminated in Primary

West Virginia
Incumbent Senator Joe Manchin ran for re-election to a third full term, but was narrowly defeated by incumbent Republican Governor Jim Justice. Due to West Virginia's heavy Republican lean, Manchin was seen as the most vulnerable Democratic incumbent in the senate up for re-election.

Republican Primary
Justice originally declined to run for the Senate back in 2021, however right before the 2022 midterms, Justice was once again considering a run. The first major candidate to announce a candidacy was Patrick Morrisey, the attorney general of West Virginia who lost to Manchin in 2018. Although Morrisey had a strong name recognition throughout the state, he was criticized for his poor campaign in 2018. The day after Morrisey announced a candidacy, Congressman Alex Mooney from West Virginia's 2nd congressional district announced he would run. A week later, George Yarborough, a rancher and businessman, announced that he would run. Finally, in January of 2024, Justice announced his campaign. Despite being the latest to run, Justice's popularity and name recognition made him the front runner. In March, President Trump went on a rally with Mooney, where he formally endorsed the congressman. Despite this, Justice was able to use his war chest to beat Mooney for the nomination Nominee Eliminated in Primary
