November’s Democratic presidential candidate Kamala Harris launched a $50 million ad campaign today, capitalizing on her momentum over Republican rival Donald Trump, including the release of a one-minute commercial titled “Fearless.” ).

It’s about her first major purchase of advertising time by Harris since she consolidated support for the Democratic nomination after US President Joe Biden withdrew from the race on July 21 and formally endorsed her candidacy.

In addition to securing the support of wealthy donors, Harris has attracted the attention of groups such as young voters, whom Biden has struggled to win over.

Polls last week showed Harris, 59, closing the gap on Trump, 78, who continues to lead in some surveys.

Ads will run on TV, streaming platforms and social media in both states in the weeks leading up to the Democratic National Convention, which begins on August 19.

The campaign’s first campaign spot opens with photos of Harris from her childhood and chronicles her career as a U.S. attorney, attorney general and vice president. “The only thing Kamala Harris has always been: fearless,” the spot says.

Since taking on her new role, Harris has focused on Trump’s felony convictions in a bribery trial involving a sex film star and other criminal charges he faces, while portraying him as responsible for a wave of anti-abortion measures in states which are led by Republicans across the country.

The Harris campaign overshadows the $10 million purchase of ad time by Donald Trump’s campaign team yesterday, which will begin in six swing states this week in response to a surge in voter enthusiasm and donations for Harris.

It was Trump’s biggest purchase of advertising time since January.
