I remember hearing a joke once that said that the definition of terms moderate or liberal was anyone with less right wing views than you. So if I was to suggest that the banker jailed last week for LIBOR (only one banker jailed? What about the rest of em?) should instead have been put in a brazen bull (preferably a hollowed version of the one on wall street! :))) and you were to disagree with me, that my friend is because your a bleeding heart liberal.
Which is exactly why Trump is on the ticket. In essence by putting this clown on the stage, he allows all of the other Republican candidates to look vaguely moderate by comparison. Fox news comes out of this looking almost fair and balanced.
Which is why his antics are tolerated, even promoted. The higher up’s in the GOP know he’s unelectable. Anyone dumb enough to slag off, blacks, Asian, latino’s and women has just cost themselves about 75% of the electorate a year before the campaign’s even begun….and its kind of hard to win an election with the remaining 25%. But the GOP also knows that the Tea Party have driven the Republicans so far to the right, its going to be very difficult for them to beat a democrat like Clinton, who will inevitably attract all the moderate voters and thus most of the swing states.
There are also a large number of traditional Republican voters who have been screwed over by the economy and are looking for someone to blame. And much as many of those same types have voted for UKIP in the UK or the FN in France, the GOP knows many of them are attracted towards crazy let’s burn the house down suicide jockey’s like Trump or Rand Paul.
So allowing Trump into the process, lets the angry white men birthers vent some steam, but also increases the chances they’ll back the eventual nominee. Who will most likely be Rubio by the looks of things.
