The Candidate that most Republicans would rather not elect

Wins his home state!  A moral victory at best.  The GOP is clearly divided, as is everything that was once deemed 'conservatism.'   That's because, in the end, conservative is a strange and elusive term.   What one is 'conserving' may well be different than what another thinks is worth conserving. 

Against this is the juggernaut that is the movement sometimes called The Left, Progressivism, or even Liberalism (though as it adopts more draconian tactics of tyranny and oppression of non-conformity, it becomes more difficult to choke up the term 'liberal' to define it).  This movement of the Left is rather homogeneous.  There are no doubt small differences. Differences in tactics, priorities, techniques. But on the whole, a person who adopts this 'leftist' viewpoint of the world in Michigan is going to be very similar to a person who adopts the same in Uganda, or the Ukraine, or Utah.  Stances on religious revelation, sexual equality, family planning, and socio-economic policies will, in most cases, be very similar.

A conservative, on the other hand, has no such unity. A conservative Catholic in America seeks to conserve very different things than a conservative of fundamentalist Baptist stripes, even if that Baptist is also in America.   Forget any similarities between that conservative Catholic in America, and a Conservative atheist in Germany.  What few topics they can agree upon will be overshadowed by their deep differences on key issues such as, for instance, the existence of God.

There was a time when those who were 'conservative' banded together, looked the other way, and decided to unite to defeat what was perceived as a common threat.  But those days are gone.  Following the disastrous first decade of the 21st century, the movement split, as each sough to hold to the purer faith, and to distance its own segment from others of the same ilk, sometimes even to the point of joining with defenders of the most left leaning agendas to attack those once considered allies in need.

So you will have a conservative Catholic siding with rather left leaning Jon Stewart or even Andrew Sullivan as they trash and slash conservative Catholic Rick Santorum.  That's the fragmentation of the force seeking to preserve the past, and that's the guarantee that those wishing to change the past will, in all likelihood, win this November.
