"Separation of campaign and state" is bad constitutional interpretation because the Constitution clearly contemplates the democratic regulation of political campaigns. There are the time, place, and manner regulations mentioned above, which are expressly permitted by Articles I and II, and the age, citizenship, and residency requirements for congressional and presidential candidates set by those same Articles. There is the 22nd Amendment, which forbids the election of the same person as president more than twice. There are the prohibitions of "religious test[s]" as requirements for public office (Article VI) and of election discrimination based on race (the 15th Amendment), sex (the 19th), failure to pay a poll tax (the 24th), and age of persons 18 or older (the 26th). The large majority of the Constitution, in fact, is devoted to setting fair ground rules of political participation in the American republic, which is precisely what well-crafted campaign spending laws attempt to do.
