According to Wikipedia, one definition of the word "default" is the following:
A preselected option adopted by a computer program or other mechanism when no alternative is specified by the user or programmer.
However dry the above definition sounds, or perhaps because it does, the words seem only to fit one person in the presidential race for 2016. It is, of course, Hillary Clinton. She is the default candidate. Though she doesn't click very well with the American public, she has what it takes: she is very experienced; she doesn't make mistakes in her pubic discourse; and she is liked by the people around her, in particular, those who have worked for her.
So who is she up against?
Bernie Sanders, whose only predecessor in American public life is a losing presidential candidate, the socialist Eugene Debs;
The blow-dried Donald J. Trump, a clever but vulgar blowhard whom the sensible American voter will ultimately reject;
The dyspeptic Ted Cruz, who seems to frost most people with whom he comes into contact;
The over-cherubic Marco Rubio, who though he looks it, is no younger than Cruz at 44;
And Jeb Bush, who can't climb out of his glasses nor his sweet reasonableness.
So America: sit back and get prepared to accept a pretty smart woman as your next President.
