Not on their own. Their impact is vastly overestimated. Not every single one of those Muslims voted in 2020 and Biden’s not going to go from 100% to 0% with that group.
Yes but given Florida was decided in 2000 by less than 1000 votes, every vote matters.
But there's a variety of reasons you could argue someone loses any close state. In 2020 for instance Trump lost GA because of a combination of Atlanta growth, higher black turnout, Dem gains in amny smaller cities, Biden flipping many suburban voters, particularly those with college attainment, failure to make notable gains with black voters, and so on. No single thing caused him to lose the state - it was the sum of all these factors.
