In this episode of Guardian Australia’s US politics podcast, co-hosts Reged Ahmad and Jonathan Yerushalmy talk about Barack Obama’s war of words with Donald Trump, after the former president spoke at a campaign rally in Ohio and compared Trump’s White House changes to the Cheesecake Factory. But how effective is Obama on the Democratic party campaign trail? What are the risks around personal attacks? And how much does Obama’s legacy help or hinder when it comes to the midterms?

Reged and Jonathan also look at the backlash over an attack ad from the campaign of Republican nominee for governor of Ohio, Vivek Ramaswamy, and why some are saying it’s a new low for US politics. Finally, how has the perception of corruption in government become such a key issue for voters on both sides of the aisle?
