If Democrats/the left could pull back enough to model the minds of Republican voters, they could have framed the vaccine as "the war against China's virus". They could have talked about a great foreign threat to our nation, and that we need to band together as Americans to fight it. Degenerates in other countries might not be taking the fight seriously, but Americans are, because we are the greatest nation on earth with the best people.

Who cares if it leaves out a lot of nuance, and is not literally true, if it works?
