In all those conspiracy to defraud and cases, the entity "fooled" was a department of the US government. It is illegal to try to foll the government. It is not illegal to try to fool the people.
There is also a proof problem. How would the prosecutor prove that the people were fooled? Many weren't. Trump was elected, after all. No harm, no foul, etc.
What do you call it when the government overthrows the people?
On your DACA argument, that didn't fly when Trump tried to undo DACA. The court said Trump could not undo DACA for existing applicants.
To conspire to defraud the United States means primarily to cheat the Government out of property or money, but it also means
to interfere with or obstruct one of its lawful governmental functions by deceit, craft or trickery, or at least by means that are dishonest. It is not necessary that the Government shall be subjected to property or pecuniary loss by the fraud, but only that its
legitimate official action and purpose shall be defeated by misrepresentation, chicane or the overreaching of those charged with carrying out the governmental intention. Hammerschmidt, 265 U.S. at 188.
looks like fisa court was deceived and its purpose of requiring spy warrant affidavits showing probable cause was defeated by a conspiracy...imho.
daca going to supreme court..obama was not charged with a crime of aiding illegal entry and he usurped the legislative laws by executive order..could he make an executive order that kidnapping is legal in some circumstances, ? methinks not...separation of powers.
