WWII training airfield selection, following the War Powers Act, 1942?

This question arose in discussions of the origins of CVG in northern KY.

Was it strictly regional politics, as suggested, including Brent Spence (the man, not the bridge)?

How were sites identified at the federal level, based on national requirements?

I would like to review original documents, news articles of the time, and any hard evidence.
