JACKSON, Miss. (AP) — Voters head to the polls in seven states Tuesday, and two of the longest-serving members of Congress face challenges that could end their careers.
In Mississippi, six-term Sen. Thad Cochran faces tea party challenger Chris McDaniel in a Republican primary runoff. McDaniel is a 41-year-old state lawmaker who led Cochran but didn't win a majority in a first round of voting.
Their battle has drawn more than $12 million in spending by outside groups.
In New York, Democratic Rep. Charles Rangel wants a 23rd term. He's still stung by a 2010 ethics scandal, and the high-profile black lawmaker also faces demographic shifts in an increasingly Hispanic district.
Voters also cast ballots in Colorado, Maryland, Oklahoma, South Carolina and Utah.
