“More than any other time, the Hispanic community, Latino community holds in the palm of their hand the destiny of this country,” Mr Biden said during a Hispanic Heritage Month kickoff event in Kissimmee.
“You can decide the direction of this country.”
A win for Mr Biden in Florida would dramatically narrow Mr Trump’s path to re-election. But in a state where elections are often decided by a percentage point, there are mounting concerns Mr Biden may be slipping, particularly with the state’s influential Latino voters.
An NBC-Marist poll released last week found Latinos in the state were roughly evenly divided between Mr Biden and Mr Trump. Democrat Hillary Clinton led Mr Trump by a 59% to 36% margin among Latinos in the same poll in 2016 — and Mr Trump won Florida by about 1 percentage point.
To regain lost ground, Mr Biden made the case on Tuesday that he would be a better president for Hispanics than Mr Trump, touting his commitment to immigration reform and a new plan to support Puerto Rico’s economy.
Donald Trump has failed the Hispanic community time and time again, and that's not a secret
“Donald Trump has failed the Hispanic community time and time again, and that’s not a secret,” Mr Biden said.
“Whether it’s in his heinous act of separating children from their families at our border, or his repeated attacks on Dreamers, or his neglect of the people of Puerto Rico after Hurricane Maria, or his repeated failures to make sure essential workers have the personal protective equipment they need.”
Still, Hispanic voters in Florida tend to be somewhat more Republican-leaning than Hispanic voters nationwide because of the state’s Cuban American population. Nationally, little public polling is available to measure the opinions of Latino voters this year and whether they differ from four years ago.
But Democrats are taking no chances. Billionaire Mike Bloomberg has pledged to spend at least 100 million dollars (£77 million) to defeat Mr Trump in Florida.
And by spending his day along what is known as the Interstate 4 corridor in central Florida, Mr Biden is devoting time to one of the most critical regions of the state.
While Republicans typically post big numbers in the northern and southwestern parts of the state and Democrats are strong in coastal cities, campaigns typically battle it out for every vote in central Florida.
Mr Biden’s first event, in Tampa, focused on veterans and was aimed at pushing a potential opening with military voters, who broadly supported Mr Trump in 2016 but are seen as potentially persuadable because of controversial remarks the president reportedly made mocking American war dead as “losers” and “suckers”.
Mr Trump has denied making the remarks, first reported through anonymous sources by The Atlantic, but many of the comments were later confirmed by The Associated Press.
“Nowhere are his faults more glaring and more offensive, to me at least, than when it comes to his denigration of our service members, veterans, wounded warriors who have fallen,” Mr Biden said.
Speaking of his late son Beau, who served overseas as a Delaware Army National Guard member, Mr Biden said, “He’s gone now, but he’s no sucker.”
Mr Biden’s decision to celebrate Hispanic Heritage Month in Kissimmee reflects a focus on the state’s rapidly growing Puerto Rican community. Many Puerto Ricans relocated to Florida after Hurricane Maria devastated the island in 2017.
