Viruses do not care about county lines. What's important to know is that the worst area ON EARTH for Covid-19 is any land within 28 miles of Central Park.
There are many larger cities on earth, with poorer health facilities, poorer populations, and far closer to the epicenter in Wuhan (which re-opened its subway system this past weekend)... but the NYC region (into northern NJ and western Long Island).
It's tough for a rational human being to blame Pres Trump for this worst-anywhere location, since the rest of the nation COMBINED does not have NYC's epidemic numbers... but of course that does not stop the psychotic Left from doing it anyway. This region has more cases than all but 4 nations on earth, including non-NYC-America. Wall them off, and save the rest of the nation the headaches.
I'm with you on that.
