Your father is typical of tens of millions of low-IQ voters whom the Republican Party has assiduously targeted since the 1968 Nixon campaign began to use the (then) newly-developed tools of segmentation by demographics. These are people who are capable only of memorizing simple-minded easy-to-chant soundbites. Trump, being a babbling moron, provides the illusion of simplicity that people such as your father crave. Reality is far too complex for their limited intellects. You are correct in thinking that Trump's return to the White House will see the end of US democracy; it is, alas, now invitable. Fortunately the surface illusion will be maintained (as it was in Rome under the Emperors - they kept SPQR on the legion's poles) and all the dullards will be happy even as their lives collapse around them. Just as it was in Russia in the 1920s.
