I was under the impression it was staggered, as in my country.

[Stand Watch Listen]

The 100 Senators are roughly staggered (est 33) in every Congression election (every two years). Wherein the entire 435 House of Representatives is up for election every two years).

[cotton1706]

The Senate is staggered. A third is up for election every two years (although we will have more than a third this time since we’ve had several senators appointed due to vacancies, Hillary’s, Obama’s, Biden’s, and Salazar’s seats)

But the entire House of Representatives is up for re-election every two years, without exception.

[calex59]

House members are for only two years, Senators for 6(unfortunately).
