I like reading these tomes attempting to apply Trumpism to some other era in history. Of course there are the nasty Nazi allusions, but on a more mellow note, this column suggests Donald Trump is the harbinger of demise for the GOP like Zachary Taylor was for the Whigs when he barely won in 1848 on a platform of bombast and how many Mexicans he had slain in the war a couple years earlier.
Of course, not all situations are the same and back then there was also the deep divide over slavery, which it could be argued was a major factor.
If the parties fade it will be people no longer feel they are relevant, and not conveniently blamed on one iconoclast.
