She has continually thanked all those essential workers, you could ask the media why they don't focus on individual nurses and praise them up. Seems people just like to try and criticize her for just about anything, think she and those around her have done a pretty good job given what was in front of them.
Seems there are plenty of people wanting to jump on the they went to hard bandwagon because not enough people have died. Guessing those same people would be screaming loudest if the death numbers had got to some of the projected levels.
Some just plain don't like her and use any small thing to have a go.
