It think you underestimate Trump influence over his followers. If he took covid seriously and right from the start advised them to get the vaccine, there would be only a tiny group of anti-vaxxers in the USA.So what would a photo op do? Trump is not a dictator like this guy. If you wanted the vaccine, go get it. If not, don't get it.
Are the people who don't care if Trump lied the same people who hang on every misstatement, exaggeration, etc., of Biden?None, but the only people that keep throwing that up is you on the left. We could care less who paid for it as long as it was built. Stopping or greatly slowing down illegal immigration was what was paramount to us, not who paid for it.
