More than 43 million ballots cast so far in midterms early voting surge
Hispanic voters have helped drive the early voting numbers, which appear to outpace overall turnout for previous elections in some battleground counties.
With less than a week to go until the US midterm elections - which will determine which party controls Congress for the next two years - more than 43 million Americans have already voted.
Data from the University of Florida Election Lab indicates that four to five million early votes have been cast each day, a much higher rate than in most previous elections.
Texas has seen the highest above-average turnout rate so far, says Professor Mike McDonald, who runs the database. Hispanic communities are also seeing a much higher turnout than usual.
"That makes sense because communities of colour are more frequently part of the Democratic coalition, and whites are more frequently part of the Republican coalition," McDonald says.
