It would be Huge if he could inspire evangelicals to the polls again.
I believe he will bring the evangelicals out to vote.
I get the feeling that the Fox gang isn’t overly supportive of Cruz because they have loyalties to the Huckster. I doubt Santorum will run - total waste of his time.
I have long argued at FR and elsewhere that for the past three decades the Evangelical vote is THE key to the GOP. If the GOP manages to arouse and enthuse the Evangelicals, the GOP wins. If they do not, they do not.
This model has been borne out every one of the past 16 elections. When the Rovian leftists/collectivists prevail the Evangelicals feel no affinity for the candidate and stay home. If the candidates can persuade and excite the Evengelicals, even when that sausion is dishonest, like W who campaigned as an Evangelical and governed like the leftist Methodist he is, they show up in droves.
