WASHINGTON - With the US midterm elections underway, former President Donald Trump embarked on a final campaign push across key battleground states as Republicans and Democrats made their final pitches to voters on the eve of voting. The 2026 midterms have been dominated by disputes over mail-in ballot procedures, with both parties closely monitoring verification processes in several key states. Trump rallies focused on energizing the Republican base while questioning election integrity, a theme that has defined much of the final campaign stretch. Election officials in multiple states reported heightened scrutiny of mail-in ballots, while both parties deployed legal teams and poll observers to safeguard the voting process. As polls opened across the nation, voter turnout emerged as the key metric to watch, with the control of Congress hanging in the balance in what shaped up as a highly competitive election day.
