I would like to call your attention to a piece by Rick Perlstein at Crooks and Liars, entitled "Forget Iowa: The GOP Always Nominates 'Next in Line.'
Perlstein points out that the last time an outsider got the GOP nomination was in 1964, when they picked Barry Goldwater, with disastrous results. Since then, the real constituency of the Republican party, i.e. the very rich who have the money to foot the bill for their endless propaganda war, always see to it that their preferred candidate becomes the nominee.
So, when Romney is nominated, and the Republican "base" marches off to the polls in lockstep to vote for him, we can once again be treated to the spectacle of millions of people being swindled once more into stabbing themselves in the back, so the hyper-rich can have even more of the country than they already own.
