Cloe Poisson / CTMirror.org A Sacred Heart University poll out Tuesday shows Connecticut residents’ quality of life has increased with renewed public optimism about the COVID-19 pandemic. Of the 1,000 residents surveyed last month, nearly 73% report their well-being as “excellent,” a small increase over a poll in March. Michael Vigeant heads GreatBlue Research, which conducted the poll. He said it reflects how residents feel about the gradual easing of COVID-19 restrictions. “I think as folks start to think about the summer, and not wearing a mask and being outdoors and being able to catch up because they perhaps have been vaccinated and catch up with a family member or friends. I think that is a big driver behind the optimism,” Vigeant said.
