Hypocrisy: The behavior of people who do things that they tell other people not to do.

President-elect /www.huffingtonpost.com/news/donald-trump/"}}">Donald Trump, who took to Twitter Thursday to blast demonstrations against his victory as “very unfair,” had a different view of post-election distress four years earlier, when he called for a march on Washington “to stop this great and disgusting injustice.”

Just had a very open and successful presidential election. Now professional protesters, incited by the media, are protesting. Very unfair! — Donald J. Trump (@realDonaldTrump) November 11, 2016

It’s bad enough that the newly elected U.S. leader this week would take to Twitter to criticize opponents for exercising their First Amendment rights, blaming “professional protesters” incited by the media. Worse, though, is that in 2012, Trump tried to incite supporters of defeated Republican nominee Mitt Romney to take to the streets in protest of President Barack Obama’s re-election.

We can't let this happen. We should march on Washington and stop this travesty. Our nation is totally divided! — Donald J. Trump (@realDonaldTrump) November 7, 2012

Lets fight like hell and stop this great and disgusting injustice! The world is laughing at us. — Donald J. Trump (@realDonaldTrump) November 7, 2012

In other tweets related to the 2012 election, some of which have since been deleted from his account but can be seen here, Trump described the Electoral College as “phoney” [sic] and called for a “revolution.”

“He lost the popular vote by a lot and won the election,” Trump said then of Obama. “We should have a revolution in this country!”

Of course, Trump ended up being wrong: Obama won both the popular and Electoral College votes.

Trump himself won this year’s vote of the Electoral College, which he attacked in 2012 as a “disaster for a democracy.”

As of Friday, he was losing the popular vote, with 60,248,555 votes, compared with 60,811,795 for Democratic nominee Hillary Clinton, according to CNN.

The electoral college is a disaster for a democracy. — Donald J. Trump (@realDonaldTrump) November 7, 2012

This election is a total sham and a travesty. We are not a democracy! — Donald J. Trump (@realDonaldTrump) November 7, 2012

Interestingly, Trump’s 2012 Twitter tantrum against Obama’s re-election may well have been the birth of his now-famous campaign slogan.

We have to make America great again! — Donald J. Trump (@realDonaldTrump) November 7, 2012
