According to a new Fox News poll, 54 percent of people favor proof of vaccination in indoor spaces like restaurants and gyms—a four percent increase from last month. An even greater majority of respondents, 66 percent, said they favored businesses requiring masks for customers and employees. The poll, which included interviews with more than 1,000 registered voters conducted between September 12 and 15, is good news for Joe Biden, who earlier this month directed companies with more than 100 employees to require proof of vaccination or regular testing.
