Romney was a decent man, but he wasn’t conservative. He was a liberal/moderate Republican. The GOP base couldn’t get that excited about yet another liberal Republican. We haven’t had a conservative nominee since 1984.
I agree. That is why Cruz might have a chance. But he could only be competitive with basically all of the GOP behind him. Romney had around 94% and lost. When you think how divided the party is - Trump v Cruz v Kasich - this seems unlikely.
Cruz would have to meaningfully open up to the moderates, without alienating his own support, plus pull in Trump support. He would not get much cross over of independents or moderates, who would probably vote for Clinton. Besides, Cruz ignites the Democrats, brings them out to the polls and unites the Clinton/Sanders groups. Cruz is at a huge disadvantage in the electoral college right out of the gate.
But I still believe there is a possibility of victory there - but only just. America is fatigued with strife/polarization, political correctness, hard left incompetency in the White House, and ready for different ideas, values. I think Cruz runs reasonably well against Hillary - her negatives once again become an issue (Trump neutralizes them).
But Cruz has to get a decent number of Hispanics, blacks, women, independents to go conservative. (?) At least he presents an authentic, principled argument for the brand (on a good day). This is where Kasich and Rubio would be an asset to the campaign and GOP message. Independents/minorities have to know that Cruz will listen to the left and negotiate/compromise. That they can live with him. (the absolute opposite of how Obama handled the right) Even I hope to get a conservative who will reach across the aisle, but not give in on key positions. That is why I like Rubio and Kasich. The simple fact of the matter is that someone like Kasich does run better in the general. The GOP has put itself in such a difficult situation. So now we put up a conservative pretending to be a moderate and hope for the best.
I have been impressed by Cruz in the campaign for the most part - he came out ok after the Heidi thing, and he is fighting Trump effectively - the whole country owes him a big thanks there, regardless of what they may think of him.

Credit where credit is due.
