Is there some evidence lockdowns work they are basing this decision on? I read articles every day saying at best the evidence is inconclusive.
Sure there is evidence! The CDC has done their own study and found the following : Lockdowns (specifically indicated by restaurant closings) reduce the slope of the infection rate curve by a whopping one percent compared to non closure of restaurants! (This was the same study I linked to previously that showed that mask mandates reduced the slope of the infection rate curve by, again, a hugely whopping one percent.) Takeaway : Lockdowns and masks work!
