Been there, done that. It's no big deal.
I've held some supremely high clearances, when I worked for Uncle. I'm talking SCI-level clearances. No, I ain't telling which ones. The point is, they don't really give a rat's carcass who you've been boffing, so long as you're not liable for blackmail. They don't care what your finances look like, beyond that you're not so desperate that a bribe would seriously tempt you. They *do* care about risk-taking behavior of the sort that makes you liable to *become* subject to blackmail, or might make you seriously unreliable on the job (such as compulsive gambling, or un-treated addictions), or might make you so desperate as you might look for radical forms of relief. They *do* care about *radical* anti-Americanism, but could care less about less radical political beliefs. Likewise, so long as you're not a Branch Davidian, or the like, they don't care about your religion, either. They just want to be sure you're reasonably stable, not insane, and not a mole or plant.
Mostly, background checks are to give reasonable assurance that you have reasonable judgement, are not an immediate security risk, and are reasonably blackmail-proof. I've got some amazing stories about the kinds of people whom have asked for clearances, and about the kinds of government-known backgrounds people have had whom had their clearances granted. Drug use? Yup, it's been waivered. Criminal records? They can be waivered too, provided you've complied with your punishments, and the crime wasn't too severe. Sexual history? For the most part the government could care less, and I've had co-workers, with the same clearences as I (or higher), that were gay, lesbian, and bi-sexual. Didn't matter - they were open, and so could not be blackmailed about it.
IOW, these 28 prima donnas are basically acting like spoiled brats, throwing a tantrum and holding their breath until they turn blue, all over what amounts to a whole lotta nothing. Who cares about a buncha spoiled punks? Let them go - they *are* replaceable.
