Not getting why your panties are in a bunchYou're not a conservative so from your position, if it's a good idea, let the govt (at the NATIONAL level) institute, plan, monitor and evaluate kids.
This argument from my POV has nothing to do with whether fitness is important. It's whether a president, AT THE NATL LEVEL, should be telling local schools that they must implement something related to fitness and then evaluate kids.
Many aspects of education are tested on a national level.
There are national-level evaluations of reading and math skills and more. How is physical fitness so different?
