The new Spanish-language ad, titled Somos Más, takes a direct hit at comments that comedian Tony Hinchcliffe made at Trump’s Madison Square Rally on Sunday, where he called Puerto Rico a “floating island of garbage.”

“Puerto Rico is an island of scientists, poets, educators, stars and heroes. ¡Boricua! We're not trash, we're more,” the narrator in the ad says.

A press release from the campaign notes that the ad will air on Spanish language TV, including Univision, Telemundo and WAPA America, as well as social media platforms such as TikTok and YouTube to reach voters.

How ballot counting will be protected on election night and beyond

More than a dozen county and city election officials spoke with USA TODAY about what they are doing to make sure they can count ballots at central ballot counting locations once polls close, no matter what happens outside.

Election officials have built new warehouses where ballots will be counted under increased security. Local and state law enforcement have run through multiple scenarios for large crowds descending on the ballot counting locations.

Some jurisdictions have reduced the number of observers allowed to attend and required them to obtain credentials far in advance.

Who is ahead in the polls?

In the final days of the election, battleground states like Pennsylvania remain tightly-contested for Democrat Kamala Harris and Republican Donald Trump and could represent the key to an Electoral College victory.

Two recent polls show just how close the race is in Pennsylvania, which is among seven swing states that could determine a victory in the race for the White House. A new CNN poll conducted by SSRS found that in Pennsylvania, the race is tied, while a new poll from Quinnipiac University gave Trump a 1-point edge on Harris.

Nationwide, Trump and Harris are tied at 48% in the latest TIPP Tracking Poll.

As the nail-biter of a race approaches its conclusion in five days, Trump and Harris plan to both address supporters Thursday in Nevada, another key swing state.

Historian who correctly predicted 9 of last 10 presidential elections picks Harris, still

Democratic nominee Kamala Harris will be the next president of the United States and beat Republican rival Donald Trump on Election Day, or so historian and election forecaster Allan Lichtman still predicts.

Known for correctly predicting the results of the last nine out of 10 presidential elections, Lichtman said on his YouTube channel Tuesday night that his prediction has not changed, despite Democratic nominee Harris' leads in battleground states shrinking and polls being nail-bitingly close.

"Nothing has changed to change my prediction that I made on Sept. 5," Lichtman said, "in defiance of the polls."

Harris campaigns in Wisconsin Wednesday night

Vice President Kamala Harris went back to a familiar place in the final stretch of her presidential campaign.

As she runs on preserving personal freedoms and protecting democracy, she made her pitch on Wednesday evening a few miles from the University of Wisconsin-Madison, where her progressive parents participated in various civil rights causes in the late 60s. She spoke at the nearly 10,000-seat Alliant Energy Center here, to a majority-female crowd.

As president, Harris pledged that she would seek common ground and common-sense solutions to problems.“I am not looking to score political points. I am looking to make progress," she said in her speech.

Trump milks Biden's garbage gaffe in insult-laden stump speech in Wisconsin

Former President Donald Trump made President Joe Biden's "garbage" gaffe a central theme in his campaign rallies Wednesday. He also continued to take shots at his Democratic opponent Vice President Kamala Harris.

“Her gross incompetence disqualifies her from being president of the United States," Trump said during a rally in Green Bay, Wisconsin, Wednesday evening. "No one respects her, no one trusts her, no one takes her seriously.”

Trump rode into the Wisconsin event in the front seat of a personalized garbage truck, donning a neon orange trash collector's vest. The move was in reference to Biden's statement Tuesday, calling supporters of the former president "garbage."
