The single most likely Republican to get coronavirus next might be the president himself

Why?

Because it is a macho thing for Trump not to wear a mask. But, not wearing a mask now is sort of like riding a motorcycle 100 miles per hour and not wearing a helmet these days. It doesn't matter how "Macho" you are if you even hit a rock or pebble at 100 mph you are going to crash just like two of Trump associates this week. First his National Security Advisor got coronavirus and now another associate, Rep. Louis Gohmert Got coronavirus. There is a 25% chance or higher at this point that the president could get coronavirus before the elections. The chance might be even higher than that at 50% (Unless the president has already been given some sort of antidote to coronavirus that the rest of us aren't aware of). (which is quite possible if the U.S. created this virus in the first place under  Trump's orders.)
