[...] I saw a "doctor" on tv say that even though the president is 74 years old and obese, he still has a 95% chance of survival so we shouldn't be too concerned.  Why can't they say that about the general population?

Ummm, maybe because, unlike "the president", who reportedly never drank alcohol nor smoked tobacco, so many members of the "general population" at or anywhere near "74 years old and obese" have developed what we've learned are called comorbidities, e.g.: heart disease, vascular disease, lung disease, liver-or-kidney disease, diabetes, or life-threatening cancers.

Oh!  Does that "95% chance of survival" include "survival" with disabilities, e.g., from the flurry of microclots, or from treatment by ventilator?  Consider Pres. F.D.R. in his wheelchair.  Recall that even previously healthy young patients have been known to "surviv[e]" CoV-19, but acquire permanent disabilities in the process.

Hey-ell, I myself am no exemplar for Trump's arguably puritanical lifestyle, and now in my late 60s, I've acquired uncounted comorbidities [#].

Note #: I'm not lacking a list; they're "uncounted" only in the sense that the count depends on how thinly one slices them, an issue exemplified outside medicine by the struggle between "splitter" vs. "lumper" taxonomists.

I think it is weird that he has the virus.  Weird that topic at debate was about the virus. 
It is upsetting. 

One of the best Presidents too.

We will pray for him and his family.

Possible scenarios- far fetched?

1-Trump and the First Lady fake their deaths from COVID and get out of Dodge to protect their lives from the Deep State- (Kind of like what Epstein did with help from MOSSAD..in reverse)

2-The Deep State has Trump and the First Lady in custody for a Bolshevik style reception in the Romanov tradition. It will be  blamed on COVID of course. Coup complete

3-Trump comes out and exposes the fake virus as the catalyst for the takeover of America by the Communists as he and the First Lady are well and can expose the BS with personal credibility and "real" data

Praying for #3

I'm thinking one of these scenarios:

1) This is a coup d'etat by poison or some germ that is duplicitously diagnosed as "COVID"

2) Trump has intel on a black swan event that is imminent, and he and his family are being isolated in an unknown location for his protection (the transport to the hospital is all staged)

3) Reports in the past 3 days of Obama's, Biden's and Hillary's deep involvement in a soft coup attempt against Trump by fabricating a "Russia collusion" conspiracy and their witch hunt against General Flynn have been ignored by the mass media. Is Trump faking an illness, thus, making aforementioned conspirators believe they're about to win, but Trump is orchestrating a "Michael Corleone" style ambush against them which will manifest as arrests. 

I hope they really have the flu and not one of the many scenarios running through my mind.

As I was saying...

Curious indeed.  But couldn't they still have the hearings online?  I mean that's what the whole country is doing these days.

[...] enough Republican senators infected with Covid-19, that there could not be enough senators "on the floor" of the Senate to cast a majority vote for Amy Coney Barrett?

I'm anxious that a Senate quorum is numerically only 2 less than the nominal Republican majority, in which I'm also anxious about having to count RINOs and the party's Never-Trumpers.  According to the U.S. Constitution, Senators cannot be prevented from attending the Senate while it's in session: "They shall in all cases, except treason, felony and breach of the peace, be privileged from arrest during their attendance at the session of their respective Houses, and in going to and returning from the same [....]" (Art. I Sec. 6 Par. 1).  So if practically necessary, there's no legal way to stop Senators who support the nomination from being wheeled in on gurneys covered by tents (as already used for transfers of contagious patients).  So vote first, sanitize the Senate chamber later.

There's room for innovative procedural maneuvering, because each chamber of Congress "determine[s] the rules of its proceedings" (Art. I Sec. 5 Par. 2).  The Demoncat-controlled House recently had the audacity to invent rules that authorized "proxy voting", to which I objected at the time (albeit not in CathInfo) as enabling vote-fraud and other skullduggery.  I don't know whether they dared defy the Constitutional requirement that attendance by "a majority of each ⟨House⟩ shall constitute a quorum to do business" (Art. I Sec. 5 Par. 1), e.g., by counting towards a quorum those members who were physically absent and voting by proxy, as if their proxy vote were a Constitutionally valid substitute for being physically in attendance.

As a matter of practical politics, the Demoncats are in no position to object to the Republican-controlled Senate doing the same, notably to consent to nominations of Supreme-Ct. justices (Art. II Sec. 2 Par. 2).  Altho' I consider the Demoncats to have sunk to such blatant lying and hypocrisy that they'll complain loud and long anyway.

Former Republican governor Chris Christie has tested positive.  

I think Europe is back on lock down.  Get ready for lockdown in USA.

Funny, I haven't heard of any Democrats testing positive or going into quarantine. By the way, do you have any links about Europe? I've been hearing rumors about them locking back down, but haven't seen any clear evidence for it.
