1. They know DeSantis is the best thing for Trumpism without Trump.
2. Vax or unvax is outdated argument from pandemic perspective. They know no unvax will get vaxxed after almost 1 year watching from sideline. Now It's booster or unbooster time. It's meaningless to ask for more vaccination. So, they take vaccination as an act of political allegiance and make it a partisan issue, not a freedom issue. They know they will lose argument if it is a freedom issue.
