Midterms: Voters, Iran tensions, and gas prices shape key races

Voters head to the polls Tuesday in midterm elections widely seen as a referendum on President Donald Trump, with high prices and dissatisfaction dominating voter concerns. Democrats aim to win control of both chambers of Congress. Roughly three-quarters of voters feel angry or dissatisfied with the country's direction, and about 6 in 10 blame Trump's policies for higher costs. Democrats are favored to win the House, while the Senate race is competitive, with key contests in Ohio, Iowa, Kansas, Texas, and Alaska. More than 59 million Americans voted early, and watchdogs worry about potential interference. Democrats have trained volunteers to monitor polling places. The results will also shape the Democratic Party's internal identity debate and test the impact of recent Republican-led gerrymandering efforts.
