Surely, the Supreme Court would hold it unconstitutional for Congress to pass a law prohibiting foreign citizens from getting up on a soapbox in Central Park and stating that they prefer one candidate or another in an American election. On what basis, then, can Congress bar foreign corporations from buying unlimited campaign advertisements advocating their preferred candidates in American elections? Ah, one might object, but buying campaign advertising is not the same as engaging in speech. And corporations are not the same as individuals. These are precisely the two principles that Messrs Kennedy, Roberts, Scalia, Alito and Thomas rejected in Citizens United.
