November's midterm elections will mark two years since Donald Trump's shock election victory – the first test of how his Republican party is faring in the eyes of the American public.
The midterms is the name given to the combination of elections for the US Congress, governorships and local races that take place every two years.
Republicans currently control the House of Representatives and the Senate – the two chambers which make up the US Congress. But pundits have suggested the elections may see a so-called “blue wave” of Democrats sweeping into power.
A liberal base hoping to derail Mr Trump's agenda has energised activists in key races, out-fundraising and out-polling a host of Republican incumbents.
The elections mark the mid point in a president's four-year term – and this year they will be held on Tuesday November 6.
