To elect President Joe Biden's successor, American citizens will nominate 538 electors across the country's 50 states. Some of these votes will invariably be won by one side or the other. However, in some strategic states, electors have shifted between voting for the Democrats and the Republicans (hence the name "swing states"). These states, therefore, play a crucial role in the election.

Since this summer, candidates Kamala Harris and Donald Trump have been concentrating their efforts on these seven states: They need to secure 44 and 51 electoral college votes, respectively, in order to reach the 270 votes needed for a majority in the electoral college, and thus win the presidential election.
