Zowie!! It also would mean Obamacare does not technically exist, because if he signed it into law while he was illegitmately holding power at the time (hence, de-factor and retroactively was not president), then the law is both de-facto and de-jure non-existent (null and void). Oh, lawyers would be arguing over that for years. Also, he could be jailed for many years, since he swore an oath to PRESERVE, PROTECT and DEFEND the Constitution of the United States. That same Constitution forbids foreign born from holding that office. If he knew he was not US born and took such an oath. It is almost as philosophical and epistomological as it is legal, in dimension!! Don’t even get me going on the possession of the nuclear codes by a unauthorized, ineligible individual.
Yes. He became privy to military secrets for which he did not have clearance. This is espionage. As for those vacations, that was embezzlement of public funds for private use. This is way way too big to even calculate just yet.
