Trump will be fine. How do I know,
So far, only Pelosi and minimal fake news is talking negative about it. The main fake news isn't really saying much besides facts, like he is positive and so is FLOTUS. Like on my news feeds, not much bad talk about Trump and CV. Normally the fake news would be printing stories as of last night on the typical stuff like Pelosi is saying. They are not biting. Neither is Biden and other wack job DNC senators like Waters, Ohmar, AOC, etc... Yet anyways. PRetty much it's only TDS'ers that are talking negative about it. Of which would not vote for Trump anyways. This actually might push those on the fence about Biden or Trump to Trumps side seeing how TDS'ers are reacting. That's why the media is not doing their normal fake news story. The media knows this and doesn't want to push those votes toward Trump.
Imagine if Trump didn't catch CV, but Biden caught it first. Biden's crew would use it to their advantage and play the sympathy card hard. I'm sure he probably wouldn't even have it, but they would make like he does to get votes.
Trumps have the best medicine and care possible. Probably even got some cool stuff we don't even know about. What ever he and FLOTUS use, will be said and if its HCQ, which he already admitted to be taking, it will further his statement about it. Of which many fake news denies works and the NV governor banned it's usage unless at a medical center, until recently.
Trump is master at 4D chess, and already has SOP's ready to go in case he were to catch CV and needed to run the country from isolation.
The only thing that can harm this country is if he dies from it. He is in the age range that has a higher chance of dying, and his weight isn't the best . He's not fat, but he aint skinny either.
