Obama and Josh Earnest have not gone as far as using the word "rigged" but they have essentially implied as much. Other large media outlets have done the same and yes, some have used the word "rigged" directly [1] (and if I dug through CNN / MSNBC / ABC reels I am positive I could find many more examples). Lesser known media outlets and internet commentators have been using the word "rigged" profusely, so it's not "nobody".
> Diplomatic sanctions have been the correct response and I don't see anyone asking for an escalation of that.
Hillary Clinton herself is on video calling for an escalation of that in the form of a military response, shortly after some saber-rattling about the US nuclear arsenal [2].
> And please remember why Russia's relations with almost all of the world deteriorated in the first place. It's because they annexed Crimea (unprecedented for our generation)
And you should remember the unprecedented actions that have caused the United States' relations with almost all the world to deteriorate. Claims of influencing foreign elections (c.f. the entire history of the CIA) and widespread hacking (c.f. the NSA essentially pwning the world) are particularly hypocritical.

The election was rigged by Russian intelligence, which was almost surely behind the hacking of Democratic emails, which WikiLeaks then released with great fanfare.
