A black who is very likely nearer to glory over a snow-white creature, is a serious antecedent and if they -white Catholics- think this is inevitable, no one will then be surprised to see a non-Catholic aspires to a mandate of the presidency, too. That is why signals are sent from time to time trying to curb his ambitions; and excuses abound: once for his origins and the other for religion. Only the interests of the majority of white Catholics will finally decide; and when you doubt, don't!
