I read the transcript of the speech. It felt more like a campaign speech instead of something to inspire as many people as possible to get vaccinated.
The carrot he offered by saying "If we do all this, if we do our part, we do this together, by July the 4th, there’s a good chance you, your families and friends will be able to get together in your backyard or in your neighborhood and have a cookout and a barbecue and celebrate Independence Day" is a complete nothing burger. Gathering outdoors with family and friends is doable NOW without people being vaccinated.
There should have been less time blaming Trump for all of the deaths and taking credit for vaccine doses that he had nothing to do with and a lot more time on the possibilities of returning to normal if everybody gets vaccinated ASAP! I think my favorite part was when he said, "when I came into office, you may recall, I set a goal that many of you said was that kind of way over the top. I said I intended to get 100 million shots in people’s arms in my first 100 days in office." Who, with a working brain, said that the goal was way over the top? We were already at the daily rate required for that before 1/20.
The absolute last thing he should have done is said to listen to Dr. Fauci. That will sour more people than anything else he could have said. The people who listen to Dr. Fauci don't need to be convinced to get vaccinated.
The entire focus of Government leadership should be coming up with ways to encourage as many people as humanly possible to get vaccinated. I don't know if they asked Trump to be in that PSA but if they didn't, they should have.
As someone who was/is a strong Trump supporter, I truly don't understand the resistance to vaccination of some other Trump supporters. He was the one pushing for the rapid vaccine development/approval and they were approved while he was still in office and his appointees were doing the approvals.
