Do u think Trump has done a good job in fighting against COVID-19? ?

Nope.  As soon as it started, he should have supporters governors in their efforts to restrict the spread.  He should have worn a mask where appropriate, and encouraged others to wear them.  Most importantly, he should have listened to experts. 

The problem is, in trump's mind, no one is an expert in anything, he appears to honestly believe that he knows more about anything than anyone.  So instead of sound, evidence based expert advice, we get the "my pillow" guy, and a radiologist who seems to think it's fine if thousands of people die.

If trump had done nothing, and said nothing, we would have fewer people who think it's a hoax, and certainly fewer who refuse to wear masks and socially distance.  By opening his fat yap, and spreading disinformation, he has exacerbated an already bad situation.  

He couldn't even protect himself from COVID-19 infection, let alone the country...

He was to lazy to do his job this is the biggest reason he lost he will be remembered as a loser . 

No. He did not. (Which was likely why he lost the election.)  He did not promote the sanitation, masks, and social distancing when it was needed until a vaccine for  the Chinese

 virus was needed.

What "fighting" would that be? Giving the early medical work to his village idiot son, for instance?

No, l think President Putin did a better job. We already HAVE a vaccine in Russia, many countries (India, Brazil for starters) have massive orders for it. India, over 100 million doses. Russians will soon have public availability. 

As for repiglican controlled Texas, COVID is spreading like wildfire. I only HOPE our flight out in two months is still a go.

As good as any human being could. 

Er, no. Which is pretty obvious from the current lack of control in the virus in the US

I don't think it is Trump's job to fight a virus.  Typically local health departments are responsible for that.  Here in Texas, for example, it is handled at the county level.

Yup and Democrats
