Democrats need to win at least four additional seats in the upcoming midterm elections to gain control of the US Senate, which is currently held by Republicans with a 53-47 majority. President Donald Trump's declining popularity and voter dissatisfaction with the Iran war and rising prices have made several races competitive, even in states Trump won handily in 2024.
Key races that will determine Senate control include Maine, where Republican incumbent Susan Collins faces Democrat Troy Jackson; Ohio, where Democrat Sherrod Brown is running against US Senator Jon Husted; Alaska, with incumbent Republican Dan Sullivan challenged by Democrat Mary Peltola; and Texas, where state representative James Talarico is running against Attorney General Ken Paxton.
Other competitive races are in Iowa, featuring Republican Ashley Hinson and Democrat Josh Turek; Michigan, with progressive Abdul El-Sayed facing Republican Mike Rogers; New Hampshire, where Democrat Chris Pappas is running against former Senator John Sununu; and Georgia, where incumbent Democrat Jon Ossoff holds a financial advantage over Republican Mike Collins. Republicans have reportedly conceded North Carolina.
