"Pennsylvania Governor Josh Shapiro responded to Hinchcliffe’s comments during an appearance on WILK Newsradio Monday morning, saying there are nearly half a million Puerto Ricans living in Pennsylvania." (This is 3.8%)
"
The Pew Research Center says Pennsylvania has the fourth-highest Puerto Rican population in the United States which makes up about 8% of the state’s population." (this might be Hispanics, wikipedia says it's 8% Hispanic)

69% of Hispanics voted Biden, 29% voted Trump in 2020.
That made up 5% of the vote. Trump lost the state by 1.2%
Trump has been ahead in the polling in PA 0.2% to 0.5% until Kamala came out ahead by 0.3% in the latest one, which puts Trump head in general.
If he loses 29% of 5% that's 1.45%
He probably wouldn't lose all of the Hispanic vote, if he lost 29% of the 3.5%, that's 17,500 votes, that could be a tipping point. The number of supporters from Puerto Rico was probably higher than this as Trump was polling way above his 2020 figures.
