Mitch McCann: US Correspondent on the impact of the attempted assassination on voting intention, JD Vance's first speech

A US poll finds the attempted assassination of Donald Trump has had little impact on voting intention.   A Reuters poll by Ipsos shows of around 1200 voters, 43% are in favour of the Republicans and 41% intend to support the Democrats.   Of all voters, 80% agreed the country was spiralling out of control.   US correspondent Mitch McCann told Ryan Bridge prominent Democrat Adam Schiff has written a letter asking Joe Biden to step down.   He says while the assassination attempt may have taken the spotlight off Biden, the issue of Democrats wanting him to step down isn't going anywhere.  On the other side of the divide, Republican vice president hopeful JD Vance is set to deliver his first speech to party faithful.   The Republican National Convention continues in Wisconsin after the attempted assassination of Donald Trump over the weekend.   McCann told Bridge the theme of the convention tonight is Make America Strong Again, with a focus on foreign policy and border security.  He says it follows last night's theme —Make America Safe Again— with a heavy emphasis on migrant crime.  LISTEN ABOVE See omnystudio.com/listener for privacy information.
