There are kids, American kids, go to bed hungry every night. People in America starve to death. They die of lack of medical care. Our very same government is cutting funding to nursing homes (so many of which are already lacking in staff and funding). Women and children are beaten, and there aren't enough outreach programs to save them all. Sexual predators can sign up on the offenders list or not as they choose -- there is no one to force them to do it! They'll only get in trouble for not signing up if they're caught doing something else.
I'm not disagreeing that a base on the moon would be an oh-so-cool idea, but how in the world can anyone put it before correcting the on-going suffering and loss of life? The lack of a minimal standard of living for everyone?
Until every single American is living above poverty level, until random wandering homeless mental patients are off the streets and in some sort of organized, supervised place, we should be focusing our attention and money towards fixing our current problems, not allowing Mr. Georgie President to distract us with the idea of a shiny new toy that we might be able to one day get.
