You SHOULD be able to know a candidate's stand on the "most important issues" instantly because you should know the candidate's political compass, principles, and philosophy.
Trump has ZERO political compass. Therefore you will never know where Trump is going to go on any of the issues on your top 100 list.
In concept, Trump likes eminent domain, and in concept, Trump likes the idea of Federally-mandated health "insurance" to "take care of everybody." THAT tells you all you really need to know about Trump's stand on your list of 100 most important issues.
Anyone who cares to look instantly assess where Ted Cruz stands on the issues because it's the same place he was 16 years ago, eight years ago, and two years ago, and very probably exactly where he'll be two, eight, and 16 years from now. Cruz plots a course and approaches issues as directed by a political compass, and always has.
Trump is guided by personal whim and "business" savvy. Trump is a classic MODERATE. You have no more idea of where Trump will stand on "the issues" in the future, than the man in the moon. Trump's lack of political compass is the most important "issue," FRiend.
Of course he does. It's nationalism. We haven't had a nationalist president since Ronald Reagan. For me that's more important than being check all the boxes conservatively correct, while supporting the dilution of American sovereignty. Cruz is a good man, but even is somehow he won the nomination the GOPe would do everything they can to sabotage him and blame his "extremism" for the loss. Moreover he won't win the nomination because truthfully he lacks the leadership skills of Trump.
