Dear Proud,
A majority of NYC did not got the virus. Maybe a fifth. It takes longer than that to get to ten million people. This is not a purely scientific response. It is a mathematical one.
It helped, that there was no setback when the Northeast reopened.
Miami had a second shut down. As well as many other cities and states.
The second shutdowns were not as harsh as the first. There was a lot more knowledge available in June then in March. This allowed for a more focused battle. (Young people partying.) And there was better testing. People could get tested and go about life. But those states are not really past their second curve yet, so let’s wait a bit to see what it proves. (How fast can they reopen.)
I have no idea what you are talking about with everything being opened. Stadiums, festivals, and concerts, are still being cancelled across the country. Viruses are not political. Are you saying that all viruses vote Republican?
