According to ChainCatcher reports, in an interview with CNN, U.S. House Democratic campaign head Suzan DelBene stated that determining control of the House may take a week or longer. This warning stems from the prevalence of mail-in voting, which has made the counting process more time-consuming.

DelBene revisited the situation of the 2022 midterm elections, during which it took 8 days to determine which party won the majority in the House of Representatives. She expects this election may take the same or even longer time. 'Some districts are very competitive, especially in places like my home state of Washington, where mail-in ballots are still being counted, the results may take longer to be revealed,' DelBene explained.

It is noteworthy that in 2022, Republicans won control of the House by a slim margin of about 6,675 votes, a result that came from the five closest districts. Some of these districts had winning margins of less than 1,000 votes. DelBene is preparing her colleagues psychologically for the possibility of delayed result announcements based on the experiences of the last election.
