Churchill and Reagan have political track records. They can be assessed based on their political accomplishments.
Trump, to date, has the political accomplishment only of being the presumptive GOP nominee.
That is to say that, in the political sphere, Trump has accomplished nothing, and to compare him to anyone with with actual accomplishments disparages those to whom he is compared.
Well put.
Yes, in the political spectrum, Trump has no political accomplishments. However, unlike godking Cruz, both Reagan and Trump have private sector experience.
