I am not going to defend the frankly pathetic response by the Trump administration, but it’s not so cut and dry as conservative governments making a hash of it while liberal governments are coping.
Coronavirus has not struck Hungary or Russia down, despite their right wing natures. More liberal governments, like Ireland. are now in lockdown. This is likely because travel from China to western Europe and America are more frequent, so you won’t have Hungarians or Russians coming into contact with where it originated*. It has also slowed down in China, which is not a bastion of liberal democracy.
There’s also the issue that this coronavirus seems more contagious than swine flu of the past, and ebola was unlikely to make it to the USA, so if Trump was president it still would have been a non-issue.
By all means criticise the idiocy of Trump’s decisions, he has made it quite clear with his actions that he’s prioritising the stock market and his own business interests above health, but I think we should be more critical of interpretations of liberal governments overwhelmingly succeeding over conservative ones.
From what I see, the strongest interpretation is that Asian governments are coping better than European and American. Most likely due to experience from the 2002-3 SARS outbreak.
*Edit: I should also add that we are unlikely to know the scale of any outbreak in Russia due to state censorship, so maybe it is worse than presented.
