Most people were talking out of their ass in January because it was very early and people knew very little. Some journalists got it wrong (usually it was the headlines that were wrong, because headline writers suck ass).
How about we get over that and fast forward to late February, early march, whenever it became apparent to just about everyone globally how serious this was.
Who took it seriously then?
Some governors did (Dem + Rep alike), some did not.
Most media outlets did
The CDC did
The President kind of did and put on a face of taking it more seriously than he was. He was still calling it a democrat hoax, not taking decisive enough action.
The
leaders whose words and actions mattered, and who had the power, failed us as a nation and as united states. Those leaders are largely Republicans. There were failures by Democrats as well (Cuomo with nursing homes, Schumer and Pelosi for no f***ing sense of urgency whatsoever, etc), but by and large, the Republican party leadership was actively fighting against decision action and messaging that would have limited the damage.

FWIW to anyone, I found a well maintained data set, though it does not have demographics:
