Any lack of chillax with the Trump supporters is due to an anti-American-voter attempt to deny the voters their choice.
Or, looked at another way, a fever is not actually the sickness itself, but the immune system's reaction to a malicious foreign invasive entity, including mutations of its own cells.
Parse it as you want. I would say, though, that the disease is not in the Trump supporters. Rather, Trump supporters are like fathers defending their families from a hoard of invasive marauding rabid raccoons in our back yard. It's the raccoons that are rabid, sick, fevered and frothing. We may be sweating, but only from clubbing the rabid animals, or running to grab our guns. Perspiration is sweat, but not fever.
As an example of a rabid feverish raccoon, turn to George Will's latest piece of foaming drool. Now that's a fever. And that's not a 'Trump supporter seeing a path to victory.'
There has been a fever, and a disease, and a lull in the fever. But better to understand which parts of the analogy apply to which players. Fevers subside when the disease is losing and retreating, or skittering away out of cowardice, if only temporarily.
That would not be those who support Trump's candidacy, ideas or policies.
Finally; somebody who understands how an immune system works, the prolific production of antibodies in the human body (or body politic) to fight off a foreign invader or pathogen.
The bodies defense system; in this case the body politic (the American people), is producing antibodies (Trump supporters), to destroy the pathogen (the GOPE), the Washington Cartel, and the Free Labor Express.
