In that case you could have looked at my Post #33 where I wrote
....which would seem to render a federal "Department of Education" unconstitutional, leaving it a state matter.
"State matter". Seems clear enough. When someone challenged me I wrote in Post #73
Was power over children's education delegated to the United States by the Constitution?
The phrase "the United States" obviously refers to the federal government (taken directly from Amendment X). So you could have looked at my Post #73, as well.
In fact I'm not even sure which of my posts you actually did read....
