So....
China supports Biden and Russia supports Trump.
I guess Iran will decide who wins the election!
. . . I doubt that. I am pretty sure that Iran supports Biden, but Israel is in Trump's corner.
OTH. . . the rest of the Five Eyes agencies? All of the common wealth, the entire realm is backing Biden.
So it will be the Saudis that determine the election?
Well. . . then you have to figure in the various dark forces and way in which different consortiums have managed to find ways to rig the election.
Both sides have perfected ways to do this.
Now, the DNC has perfected something called "ballot harvesting." They do this in California, and down in Dade county, Brenda Snipes in infamous for having Debbie Wasserman Schultz keep her seat in congress, when she definately should have lost it. The DNC KNOWS how powerful a tool mass mail in voting can be, if used as a way to corrupt an election, they have already used it several times.
OTH?
The Clinton campaign and the neo-con side of the GOP has been using Crosscheck and voter purging. These means were used in the BUSH v. GORE election, and have been used many times since to skew results, and political scientists know something is funny when the stats are so wildly different than the exit polling. Now, the corporate media will tell you that is a result of the absentee ballots, and folks being dishonest in exit interviews, etc., but for a century, those were the most accurate predictors, and now? The elite media wants you to disregard the most accurate polling ever done?
nah.
oh. . . and don't even get me started on the shady connection within the interlocking directorate of the board members on which corporations own your electronic voting machines, and how vulnerable those are to vote switching. . .
We've all heard the stories, even a teenager can hack some of those. They are simple machines, and the code could be easily given away as a campaign gift to an incumbent. I know of several good documentaries, if you are interested.
To sum up? I think the least of our worries are "foreign interference," if you truly care about electoral integrity, but honestly, I don't believe any of the mainstream candidates really care. Nor does the press, they only want you to lose faith in the system and hate the outsider.
And most political scientists worth their salt would tell you the same.
