Why would anyone have believe the old airbag's pledge, in the first place? If Trump(et) is anything...it is NOT consistent.

Given what their leaders have been doing (and not doing recently) perhaps it's time that the Republicans went the way of the Whigs?

Some might say that this has been Trump's (the statists) plan from the outset: Split the outraged so-called conservative votes by providing a false anti-insider candidate.
Its all a sham, and a lie, and a con by the statists to retain power in spite of their obvious betrayal of the ideals Americans value.
Stop wasting your votes on statist looters.

"leads Trump to believe that the RNC, like his opponents, is controlled by special interests and high-dollar donors who don’t have the well-being of the American public in mind."

As opposed to Trump who is "controlled" by one (or more) high dollar donors and doesn't have the well being of the American public in mind.

As they say in Bangkok, "same, same"

Even if the RNC stacked the deck against him they would have to know exactly what they were provoking - his departure and a boat load of votes along with him.

I will say that the audience certainly seemed pretty biased and with Trump polling in the mid 30s you would expect him to have the largest group of supporters. It certainly looked like there was an attempt to shout him down from the audience and wildly applaud some relatively unremarkable statements by others, particularly Rubio.

Now Trump is certainly not the picture of decorum but I think there is something in what he is saying. It's no secret that the establishment doesn't want him in the race. They may be moving to the next level. For some reason South Carolina tends to be the home of really nasty tricks.
