But this is too difficult to achieve. Personal lives of former presidents and active politicians are evidence of it. Several religions have tried, during millenniums, to change human nature. Most unsuccessfully, even among priests themselves. But they are still trying.
European nations act differently.
Personal morals are kept personal as long as they don't interfere with public affairs. There, a campaign to peruse into a president or a chief of government's private life is something unthinkable. Moreso when the matter is a relation among two adult persons acting on their own decisions and by mutual agreement. As generally expected, the American legislation on matters of sexual molestation, and the possibility for criminal charges for that cause, has not changed much the relation between the two sexes. But unscrupulous persons can use it to achieve notoriety or financial advantages.
