Some of the migrants flown to Martha’s Vineyard this week said they were grateful to Florida Governor Ron Desantis, calling his move to transfer them to the posh seaside community “a stroke of good luck.” “The life there is good,” said Eliud Alguilar, a 27-year-old from Venezuela in an interview with The Post, referring to a military base where he and the 49 other migrants were sent by Massachusetts authorities after they landed in Martha’s Vineyard this week. “They treat us well, they provided us with food and medical assistance. We are all well.”
