Long post here, Walter. Obviously you don't have to read it - but as a Canadian who loves Trump, I can't help but feel like I could do something to help stop these pathological freaks from burning down their own cities. American politics and economics massively affects Canada, and that's why I'm so passionate about it. More than I am about Canadian politics - with 2020 being an exception, or at least a tie, because Covid-19 has made things nutty here too...putting it nicely. More like: outright batshit. At this point, I don't know which of our country's is dumber. But if you put a gun to my head...I'd say Canada].
I assumed that if there are ever any Supreme Court judges who die in office, that the sitting president gets to replace them with his choice of judge - whether one SCOTUS justice dies during a president's tenure, or whether they all do. But a Canadian liberal friend told me about an incident with Obama in 2016, after Justice Antonin Scalia died...which gave me pause for that [link below]. I guess this isn't a strong objective constitutional process, and that if you can delay the new judge with gridlock in the house or senate, or congress...maybe the matter is not an objective one after all - and more one about political might. My friend is smart...but he's also a Canadian leftist, so I always research information he gives me, to make sure he is accurate. Here is the case involving Obama's Supreme Court nominee that he said is similar Trump's current situation:

That being said, barring MASSIVE electoral fraud [which is definitely a possibility], I don't see Trump losing 2020. Biden's worsening dementia memory recall issues seem to be getting worse by the week at this point. And I mean that - I swear, just last week [or at least, earlier in the summer], he was speaking faster than he is now. I think at the current rate of his cognitive decline, that he's going to be reading things like "[brief pause]" off teleprompters.
Serious question, Walter: is Biden's presidential big being pushed by Democrats, knowing that his chances of dying in office are probably 40% or higher, so that Kamala Harris can become the president? I've literally never seen a candidate with Biden's cognitive state being ran anywhere on earth, for any political position in any form of government [aside from a loopy former local communist City Counsellor, who would consistently fall asleep at City Council meetings] possibly anywhere in the HISTORY of politics at all.
And even if Joe Biden has no cognitive issues, he is turning 78 in November. That would make him by far the oldest first-term president in history - by almost a decade [Trump was the oldest and holds the record thus far, at 70, 7 months, 6 days on his inauguration day in 2017, and Ronald Reagan was 69 - 17 shy of his 70th birthday on his inauguration day in 1981].
It's one thing to be 7 years and 7 months older than the OLDEST first-term president in AMERICAN HISTORY - some would say that's remarkable, although I would say it's as concerning as it is impressive from a record perspective - but when that near decade in age shows completely - and is literally showing more and more with each passing month at this point [frankly], then...yeah, I consider that a concern.
I would go so far as to call it elder abuse. I was saying that somewhat jokingly at first [not so much as a knock on Biden, but as a knock on the Democrats for not finding a more fit candidate to run as president], but now I actually mean it. And while I feel we can objectively say that Biden as memory recall issues, comments about him potentially having dementia are unsubstantiated. That said, the more I hear him talk...the more I really do think he is showing signs of dementia. Not "early onset dementia" [I think that term is reserved for those who get dementia before the age of 55], but the "early signs of dementia", which is a regressive and irreversible cognitive disease, that we will see get worse before our eyes if Biden does in fact have it. And if Biden is otherwise healthy, he could still live another 5-10 years, so we could well see a man with full on Alzheimer's Disease in office if he is elected, does actually have Alzheimer's, and we see the disease progress [regressing his cognition] as his presidential term goes on. 
I can't imagine him winning. I'm not saying this just because I want Trump to win, but if a president has a proven [not yet the case] regressive cognitive disorder...I think that should require an examination by the president's personal physician AND a nonbiased geriatric psychiatric, if not [better yet, IMO] a team of geriatric psychiatrics [psychiatrics, unlike psychologists, are medical doctors] and aging specialists, to objectively ascertain a president's cognitive state, and mental fitness for presidency.
That being said, I guess nothing in the constitution requires that...and if that is the case, so be it. I guess The Founding Fathers - the genius White men who scripted The Constitution, and the other genius White male founders of the USA who brought us The Bill of Rights in the USA - literally the most progressive legal documents in human history at the time [thank a White man for that
] - could not have predicted all the things happening today. They put everything they possibly could in place to prevent this...but hey, evolutionary happens, empires die, and Jews still dominate the media and investment banks.
There are probably more card-carrying Democrats voting for Trump this year than ever before because of how insane the riots in Democratic cities got, on top of the anti-police sentiment, district attorneys refusing to even charge criminals literally caught on camera committing crimes, and the gated communities of Democrats being invaded, and Black- and POC-ran businesses being burned to the ground in the name of "racial justice". 
Barring massive electoral fraud [definitely possible], I can't imagine Trump losing this year.
Hopefully Trump wins handily, and without reelection pressure to worry about, starts sending out the National Guard and other federal law enforcement to put an end to riots in Democrat-ran cities, defunds all "progressive" mayors and governors who let that continue all summer, and put traditional law and order back in place.
Then again, lazy unemployed "Social Justice" BLM rioters will stop rioting as soon as the weather gets cold...they always do.
Matt,
The Democrats had to subvert Bernie Sanders taking over their party, so they fixed the nomination for Joe Biden. Biden was one of the worst of the 24 people seeking the Party nomination, but the out of touch old guard Democrat leadership knew they could easily control him. This was a clear indication that after 3-1/2 years of President Donald Trump the Dems had done nothing to groom a candidate to defeat President Trump. So for the last four years their Party has not only stagnated, it has regressed into a mix of AOC’s absurdity, Pelosi’s senility, and a hope that the young party members could be convinced Joe Biden could deliver a third term of failed Obama policies. The MSM has not only been complicit in this fraud, they actually act as the PR arm of the DNC. The MSM role has been to steer the narrative away from the never ending list of Democrat failures and downplay the historic successes of the Trump presidency.
Make no mistake Matt, Joe Biden is nothing but camouflage for the socialist-Democrats. They have no intention of letting Joe Biden run the country. Joe is just the senile old man they hide behind, to cloak their tax increase and give away program agenda. The basis of the Democrat Party new policies is not to spread America’s great wealth to the less fortunate, it is to line their pockets and buy votes to remain in power, nothing more.
I think the American voters see through this thinly veiled version of communism and will soundly reject the Democrat ideology. President Donald Trump will win in a landslide and take majority control of both Houses. It’s not the next four years that America and her allies should fear...it is the four years after that. Unfortunately for Canada, your economy is heavily dependent on the U.S., yet your pantywaist liberal PM goes out of his way to try to attack the American President and win favor by being part of the so-called “Trump resistance”. Trudeau just ends up looking stupid, weak, and causes further damage to your economy.
If the past 4 years has shown us anything it is that liberalism is a sickness and it has to be stopped. In a two-party system, we have one party who are running on a platform that basically amounts to “Orange Man Bad”. I often joke that the internet and social media have dumbed down America. I am absolutely certain that you will see that reflected in the support for the Democrats in November. The problem with stupid people is that they don’t know they are stupid.
