It's a fair question

Romney is apparently able to stay credibly close in the polls no matter how egregiously evil, incompetent, or treasonous his behavior.  Amazingly, he might still win, despite verbally urinating on half the American people.  It's not real likely on today's numbers, but maybe he has a 30-35% chance.

I think it is time to bust this out again:

 

But if elected, brace yourself for breathtaking incompetence.  An overconfident man, his principles softened by a lifetime of entitlement, his heart hardened by decades of separation from normal people, a man inexperienced in the facts and details of national politics and without natural political allies in Washington...he could make Franklin Pierce look like Franklin Delano Roosevelt.

Left, right or center, you do not want this.
