Henry Olsen: US Pollster on the debate between Kamala Harris and Donald Trump

Early Edition with Ryan Bridge

A heated exchange between the two US presidential hopefuls - with many saying Kamala Harris got under Donald Trump's skin

The pair faced off over inflation, abortion and foreign policy in a high stakes debate in Pennsylvania.

US Pollster Henry Olsen told Ryan Bridge that debates in the past have had a minor effect on the polls, but this race is so close that even a minor effect could transform Harris from an underdog to the favourite.

This debate could have an impact on the polls, he said, but we won’t know for at least another week.
