Republicans say President Trump’s decision to make Hispanic voters a priority is boosting his support with this critical bloc in public opinion polls and threatening Democratic nominee Joe Biden’s prospects in key battleground states.

Trump received 28% of the Hispanic vote four years ago. But a fresh national poll from Quinnipiac University pegged the president’s support with this demographic at 36% — despite trailing Biden by 10 percentage points overall, progress reflected in other surveys conducted over the summer. In swing states that will determine the outcome of the presidential race, that level of Hispanic support could push Trump over the top in a close race.
