One of the notable things about this recent election was how Big corporations were almost entirely on the side of and supporting the main candidate of the left whilst opposing the main candidate of the right. Clinton was supported by numerous top CEOs and big corporations. Trump, whilst he was supported by a few notable very wealthy individuals they were very much the exception. He did not get the support of any major corporations or CEOs and the bulk of the billionaire class opposed him.
Now a large part of the left like to spin this narrative that whatever big business do is of the right and the left is always opposed to big business interests. So they spin this by saying that Clinton wasn't on the left at all but rather on the right!!! In this narrative Trump was just a bit too right wing for the big corporate bosses so they went for the more moderate right wing Clinton! Of course this is complete nonsense. Hillary Clinton has been a dedicated leftist for nearly fifty years, Trump was the only major party candidate on the right.
In my view the real reason is that big corporations overwhelmingly backed the left wing candidate because big corporations overwhelming lean to the left. As was pointed out on a recent Breitbart article on the Breitbart spat with the Kellog's company "Corporate America is more left than right"

I think it was explained very well in an article from last year from right wing British journalist Ed West
http://blogs.spectator.co.uk/2015/05/why-is-big-business-so-interested-in-left-wing-politics/I'm sure the reason so many leftists can't see this is that they're so enamoured of their fantasy of being the litlle guy standing up to 'the man' that they refuse to see that 'the man' is not only on the left himself but is the driving force behind the funding of leftist activists.
