The nominees on Democratic tickets spent the final day of the US presidential campaign rallying supporters in critical battleground states, CNN reports.

Vice President Kamala Harris spent the day in different parts of Pennsylvania as her campaign officials projected optimism about what they’ve frequently called an aggressive ground game in the state while acknowledging it’s going to be a close race.

According to CNN, her campaign will conclude later tonight with a rally in Philadelphia. So far, she’s gone door-knocking in Reading, presented a vision of unity and togetherness to people canvassing for her in Scranton and declared her long-standing commitment to Puerto Rico in Allentown.

Spending his day in different parts of Wisconsin, Vice-presidential candidate, Minnesota Governor Tim Walz, touted Harris’s record and credited her for bringing “back joy to the politics”.

He projected optimism for the polls, when voters get to “shape the future for generations to come”, CNN adds.
