DURHAM, N.C. — By Tuesday night about 90 million Americans will have cast ballots in an election that’s almost certain to create greater partisan divisions, increase gridlock and render governance of our complex nation even more difficult. Ninety million sounds like a lot, but that means that less than 40 percent of the electorate will bother to vote, even though candidates, advocacy groups and shadowy “super PACs” will have spent more than $1 billion to air more than two million ads to influence the election.

There was a time when midterm elections made sense — at our nation’s founding, the Constitution represented a new form of republican government, and it was important for at least one body of Congress to be closely accountable to the people. But especially at a time when Americans’ confidence in the ability of their government to address pressing concerns is at a record low, two-year House terms no longer make any sense. We should get rid of federal midterm elections entirely.

There are few offices, at any level of government, with two-year terms. Here in Durham, we elect members of the school board and the county sheriff to terms that are double that length. Moreover, Twitter, ubiquitous video cameras, 24-hour cable news and a host of other technologies provide a level of hyper-accountability the framers could not possibly have imagined. In the modern age, we do not need an election every two years to communicate voters’ desires to their elected officials.

But the two-year cycle isn’t just unnecessary; it’s harmful to American politics.

The main impact of the midterm election in the modern era has been to weaken the president, the only government official (other than the powerless vice president) elected by the entire nation. Since the end of World War II, the president’s party has on average lost 25 seats in the House and about 4 in the Senate as a result of the midterms. This is a bipartisan phenomenon — Democratic presidents have lost an average of 31 House seats and between 4 to 5 Senate seats in midterms; Republican presidents have lost 20 and 3 seats, respectively.
