Thirty-four of the 100 total Senate seats are being contested in November, the result of a staggered election system.
The 2020 US election has been dominated by the battle for the White House between Kamala Harris and Donald Trump. However, on November 5, Americans will also be voting for other key positions outside of the presidency. These races will determine who controls Congress, with 34 Senate seats and 435 House of Representatives seats up for grabs.
Staggered races in the Senate
The Senate’s staggered system dates back to the country’s founding when senators were divided into three classes with varying term lengths. This system ensures stability in US politics, with two-thirds of senators remaining in office during each biennial election.
How does this compare to the House of Representatives?
In contrast, all 435 members of the House serve two-year terms and face re-election at every vote, making them more vulnerable to turnover.
What could happen on November 5?
The Democratic Party currently holds a slight majority in the Senate, with Republicans needing a net gain of one or two seats depending on the presidential election outcome to gain control. Meanwhile, the Republicans aim to defend their House majority, with several toss-up races expected.
