lol...What evidence is there that Republican establishment would ever endorse a hardcore pro-lifer opposed to gay marriage that would put judges on the Supreme Court that would overturn Roe?

Huckabee repulses the Republican establishment. There is no chance it would ever risk getting behind him.

Now, one could make the case the liberal media is pushing Huckabee to divide the conservative vote and prevent a Scott Walker or Ted Cruz from winning the nomination.

Most of the people who get accused of being Republican Establishment nowadays aren't pro-abortion (or at least they don't claim to be). Whatever the GOPe is today, it's not what it was forty or fifty years ago.
