1. In February 2020, Trump tried to close our Western border to Chinese flights. Nancy Pelosi went to San Francisco and stood in the middle of a crowd saying, 'You don't need to wear masks, you don't need to be afraid, you can go out to eat.' She and her cronies shouted Trump down as a xenophobe when we knew the virus was inflicting carnage in China. So at that point the situation was painted by Trump's opposition to be, "He just hates travel, he's overreacting, etc". The Democrats were the ones spreading confusion and lax mindsets at that time. This did change months down the road, when the Dems finally got on the safety train and rode it so hard and fast that most Republicans didn't want to follow because they feared the requested measures like mass lockdowns and mask mandates were illegal. This was all compounded by different studies and doctors saying wildly different things, state authorities all taking different routes to respond, and of course people making it 10x worse by barely researching anything before going to social media and dangerously scaring their friends or convincing them it's nothing to worry about. So to say the optics during that entire multi-month fiasco weren't screwed over royally by most people at every level, and that Trump alone is solely to blame for everything, is an attack simply not historically accurate.
2. Look at the Federal response across the board after a state declared a state of emergency. They got relief supplies like PPE and ventilators moving. They sent a hospital ship to New York. They never tried to say a state couldn't impose a lockdown, mask mandate, or anything like that; it was a hands-off, 'I'll help if you ask' approach. Even then- Governor Cuomo, if you'll recall, praised Trump's help in New York state. And of course, the Fed coordinated virus research efforts via the CDC and poured resources into development of the vaccine.
So to anyone looking solely at Trump for their daily dose of fear, yeah; you got the impression that until you got a vaccine you were on your own. But that is an exceedingly narrow window through which to view the picture.
