The argument could be made (mainly by those who want to take us back to a mythical innocent time of the supposedly recent past) that it's advertisers who've corrupted our culture and changed what's socially acceptable through their manipulations. Or, if you have sold your proverbial soul to the gods of unfettered commerce — like the rightwing self-described Culture Warriors, or the (formerly) Moral (former) Majority — advertisements are the market speaking for the greater culture at large. And the greater culture, funny enough, largely disagrees with the rightwing.
You can think of the market as a leading indicator of our social mores and the Republican primary as a lagging one.
The GOP-worshipped market has chosen the winner of the culture wars, and it hasn't looked favorably on its most devout.
Of course, the market for Republicans is just like the Bible or the Constitution. They worship it piously as long as they believe it agrees with them.
If their deified market is all-knowing and all-powerful — it clearly favors a progressive social agenda...and not the GOP's.
