Several closely watched House and Senate races remain highly competitive just hours before Election Day. The contests have continued to shift during the final days of the campaign, keeping the overall electoral map broader than previously expected.
Early-voting data, polling and advertising spending are among the factors shaping the latest assessment of the races. Together, they indicate that a wider group of contests could remain in play in both chambers as voters prepare to cast their ballots on Election Day.
The late movement leaves key outcomes uncertain and ensures that competitive races will draw particular attention as voting concludes.
