In a county where more than half of the residents are born outside the mainland U.S. — mostly in Latin America — Trump has outspent Joe Biden’s campaign by about $4 million on TV in the Miami-Fort Lauderdale media market, much of it on Spanish-language ads. The president’s conservative allies have dominated Spanish-language social media and WhatsApp messaging to Spanish-speakers. And the Miami-Dade County GOP has fielded candidates in five key local races, all of whom are Cuban-American, which could help turn out the pro-Trump Republican vote…

“They’re not hearing enough from the Biden campaign, and I think the Biden camp has seen that and beefed up their programming the last two weeks to head into the general,” said Ricky Junquera, a state House candidate and vice chair of the Miami-Dade Democratic Party. “I’m sure they’ve obviously identified that’s a problem and they need to correct that quickly.”

Miami state Sen. Annette Taddeo, a Democrat, said the raft of polling and the late-breaking response to Trump’s threat in Florida has the party taking the matter seriously after months of discarding warnings.

“Some of us have been warning about this, but it was kill the messenger: ‘You just bitch about everything.’ And now they’re like ‘Ahhhhh! What do we do?’” she said.
