I was screened for COVID this morning before I was allowed into a hospital pharmacy. Nurses in protective gear asked me a few questions and took my temperature by putting a device into my ear. It took less than a minute. When I got inside the pharmacy we all stood at least 6 feet from each other. We can do the same thing at the polls. It is easy.
The only issue I’d see is that poll workers are always women over 80 years old (at least that’s been my observation over the last 25 years of voting). They might want to get some younger people to work there.
