A former US Treasurer says he hasn't seen this level of support for the Democrats since Barack Obama's presidential campaign.  

The Democratic National Convention starts in Chicago today. 

It's where Vice President Kamala Harris and her running mate Governor Tim Walz will accept their presidential and vice presidential nominations. 

Former Democratic National Committee Treasurer Bill Derrough told Mike Hosking that Harris has some serious momentum.  

He says there's tremendous energy, and a feeling like they haven't felt since 2008 with Barack Obama, maybe even greater than that. 

Derrough says there’s still some sadness around Biden stepping down, but it’s worked out for the best. 

He says it couldn't have come together in a better way, supporting Harris and Walz, and making a symbolic handover at the first day of the Convention.
