What’s at stake? Will voters show up? And who is looking to make history?

US voters go to the polls on Tuesday to take part in midterm elections that will help define the remainder of President Donald Trump‘s term in office.

In the House of Representatives, all 435 seats are up for grabs. Thirty-five seats in the Senate are up for election, as well as 39 governorships in 36 states and three US territories.
