I believe that it’s way past time that a “traditional” Republican challenger should have outdistanced the pack, and as it is, the only current “leader” is Mitt Romney, the apparent choice of the dimmacrat media. There is something sick, sick, sick about that. Now we have Trump, showing all of the rest the way, saying exactly what they all should have been saying, with only Palin and maybe Cain coming close. All the rest have been castrated by PC.
Welll....certainly, "PC" is part of it....but there are other reasons.
The rest of the politicians have to be careful because:
if they lose, it will hurt them politically in the future (it won't hurt Trump at all),
In the politician's world, they all have things to hide knowing that if they attack their fellow politician, they can be attacked back (Trump could care less),
a true politician is no longer capable of "telling like it is"; it's been so long since they told anything approaching the truth that they no longer recognize it for what it is (Trump has no such history or limitations.)
