He did not fail on the scaling or the delivery. His plans provided for scaling up and options for more vaccines with companies and Biden exercises them as needed per the original Trump plan. In regard to delivery, Trump went through the start-up head-aches that every country has gone through and most have done worse. Joe came in after the vaccine was developed and after the initial start up problems were sorted out. This is how it goes in the business and government program world, eh? Start-ups and those responsible do the heavy lifting.
Biden and Obama are the same clowns who brought you the total, total Obamacare shiite-show launch and website fiasco, yet you like to think that those geniuses would not have had any of the start problems that Trump had to deal with. The delivery level that is occurring under Biden is not that lofty a goal or that heavy a lift. Biden is just playing Santa Claus handing out Trump vaccines. As I have said many times, this country does in excess of 3 million flu shots a day in normal flu season so the covid level is not anything spectacular. Bringing vaccines to market 4-8 years earlier than the norm- that is spectacular.
"Thank you President Trump" is what you meant to say
What's Joe doing today? Oh, I see. He is doing a great job of "distributing" Trump vaccine to Mexico and Canada.
