Tomorrow’s midterm elections will mark two years since Donald Trump’s shock election victory in 2016.
These midterms are the first test of the Trump administration in the eyes of the US public.
Republicans currently control the House of Representatives and the Senate – the two chambers which make up the US Congress.
The elections mark the mid point in a president’s four-year term – and this year they will be held on Tuesday November 6.
How do the midterms work?
All 435 seats in the House of Representatives will be voted on in November. Representatives serve two-year terms so the entire house will face re-election in 2020.
35 out of the Senate’s 100 seats will be on the ballot. Senators hold six-year terms.
36 state governors are up for election.
How will they affect Donald Trump’s presidency?
The elections will shape US politics for at least the next two years.
A Republican-controlled Congress will make the final two years of Mr Trump’s first term much smoother – Allowing Trump to continue funding his wall, pass further tax cuts and attempt to repeal Obamacare.
If the Democrats win enough seats, they could kill the Republican legislative agenda.
A Democratic majority would also see the party gain seats on Congressional committees with the power to investigate the Trump administration.
