Your source got their numbers from twitter posts. What do you think "skeptic" means? Because it doesn't mean "accept anything at all as long as it agrees with what you want to be true."
And frankly even if he did get the popular vote this was the lowest voter turnout in decades. Trump wasn't popular, he was just slightly less unpopular.
Also, the fact that the vote was so close makes it great grounds for a civil war, or a similar conflict. Whenever a big vote is 50/50, there's a risk.
People are clearly getting divided into two, and it's something to be wary of.

Load of crap. Less unpopular.
He had to be massively popular to get more REAL people's votes, MORE than Hillary did with the rigged voting machines (people actually saw their vote for Trump flip to Hillary, and in Texas if one voted straight party ticket for Rep, the vote flipped) and where huge numbers of dead people walked to polling stations to vote Hillary (Democratic poll watchers and "get out the vote" Democrats have admitted they would register people to vote based on a name on a tombstone, and some were caught manufacturing votes)... as I said, he had a landslide so large it overwhelmed the stolen and invented votes by a wide margin.
It's funny how you can make up whatever you want.
He did not have a landslide. He had a grand total of 26% of the vote, regardless of how much Hillary got. And that's the people who voted, we had the lowest turnout in 20 years so it's an even smaller fraction of people who are registered to vote... which is itself a smaller fraction of our entire population.
Frankly I think their whole plan was to scare everyone away from showing up, except for right wing extremists so they could get the house and senate. Which worked. I wrote more about it here: https://steemit.com/trump/@telos/election-thoughts-it-s-an-elaborate-ruse
But you have no proof anything was rigged anyway, so yeah... least popular president in decades no matter what.
