Everything you need to know about the midterms

In this episode of Guardian Australia’s US politics podcast, co-hosts Reged Ahmad and Jonathan Yerushalmy take a special look at the midterms which are coming up in early November. All 435 House seats are up in this election as representatives only serve fixed two-year terms. In the Senate, 35 of 100 seats are up for grabs too as senators serve six-year terms.

What are the factors that could instead allow the Republican party and the Trump administration to hold on to power in Congress? They also look at why US ambassador to Greece Kimberly Guilfoyle has been ousted from her job – and whether criticism of new White House press secretary Katie Zacharia is fair
