The GOP was confident about keeping its Senate majority. Now the fight for control is wide open

Control of the United States Senate has become increasingly competitive as the November election approaches. While Republicans previously held a projected advantage for the final two years of President Donald Trump’s term, the current political landscape has shifted, leaving the majority status of the chamber uncertain with less than two months remaining before voters head to the polls.

Key electoral contests are currently underway to determine the balance of power, including high-profile races for open seats. In New Hampshire, voters are participating in primary elections to select candidates for the seat currently held by retiring Democratic Senator Jeanne Shaheen, a contest that both major political parties are actively targeting.
