Today it’s Cardi B, yesterday it was J-Lo.

Kamala Harris has been rolling out the celebrity endorsements in the final days of the campaign. At her rally in Milwaukee, Wisconsin, the rapper and songwriter was one of the key speakers and performers before the vice-president took to the stage.

Cardi B’s a social media juggernaut with more than 250 million follows across her social media platforms. It’s unlikely her appearance will win over Maga-hatted Trump Republicans. But it will help energise Harris’s base, and potentially encourage some fans who might not have thought about voting to bother to.

What was noticeable was that Cardi B rehearsed many of Harris’s own talking points ahead of her taking to the stage.

Reading off her mobile phone, she laid into Donald Trump's policies on abortion rights, saying: "No, no. I'm not taking any chances with my future...and [I’m] taking no chances with the future of my children".

On the economy, the rapper said it needed "to get stronger" and added "that the cost of food and the cost of living is too high".

Harris has recently begun putting the economy near the top of her speeches, and that was no different tonight.

"At the top of my list is bringing down the cost of living for you that will be my focus every single day," Harris said.

The cost of living is a major issue in this election, as households balk at prices that have jumped nearly 20% over four years.

In the final days, she’s making a pitch that she understands ordinary Americans' economic pain and has a plan to help. If America is listening, we’ll find out soon.
