Biden is getting trounced with Cuban American voters in Florida, a trend that could tip the state to Trump. Will it all come down to Florida in November? Former Vice President Joe Biden is underperforming with Cuban Americans in Miami-Dade, the largest county in the state, as well as with Latino voters across Florida, according to recent polling. The lack of support from Latino voters could cost Biden a win in Florida, which has backed the national winner in every election except one since 1964. Ref. USAToday.
