There was really NO pro-Hillary support of substance.
Hillary won the popular vote by nearly 3 million. This is plenty of substance. And before you say that our Presidents are not elected by the popular vote, I know that. But that does not make the popular vote unimportant. Trump cannot claim to have a "landslide" or a "mandate from the American People" without it.
Donald Trump displaced 17 or whatever Republican Primary opponents, all with some claim to being qualified, only one or two will any real following, support for their personal positions, and even those came around to offer support to the man who was elected as our President, albeit grudgingly.
The GOP put up a list of idiots and generally unelectable persons. Rising to the top of that list did not mean so much.
