"Of all the Presidents in the more than 200 years the US has existed, Donald Trump is the least suitable--he is even worse than George W. Bush. Oh yes I can...."

I'm not sure of your familiarity with the U.S. presidents of the past 200+ years, but I'm sure you know of their qualifications. I stand corrected. But considering qualifications to hold the office of POTUS is be a naturalized citizen at least 35 years of age, was Trump not born in NYC or he doesn't meet the minimum age requirement? If one of those is true then yes - he is definitely is not suitable for the job.
