Donald Trump has always been outspoken where President Obama is concerned, expressing his doubts on the validity of the President’s college records and his birth certificate. 

Just moments after the president’s victory was projected by various media outlets last night, Donald Trump took to Twitter to voice his outrage, demanding a ‘revolution.’

Trump strongly believes that the Democrat’s re-election to office was a ‘great and disgusting injustice.’

Earlier Tuesday, the embattled real estate mogul took to the microblogging site reminding his followers: ‘Whoever wins today, remember that tomorrow we still have a country struggling. 

‘Our work is not done until America is strong again.’

However, when it became apparent that former governor Mitt Romney would not be the victor,  Donald’s tweets became more enraged, and more hyperbolic.

Trump began with: ‘Well, back to the drawing board!’

Trump swiftly followed up with a call to revolution,  writing: ‘He lost the popular vote by a lot and won the election. We should have a revolution in this country!’

He later deleted that tweet.

But The Donald was far from over. ‘This election is a total sham and a travesty,’ he wrote. ‘We are not a democracy!’ He also added the ‘serious and unprecedented trouble’ that America is in – ‘like never before.’

The 66-year-old later went onto attack the Electoral College, who ultimately chose Obama as our leader once again, but offered a bit of hope for the still-Republican House of Representatives.

‘Hopefully the House can hold our country together for four more years,’ Trump tweeted. 

‘House shouldn’t give anything to Obama unless he terminates Obamacare.’ He did not tweet anything after Romney’s gracious concession speech.

Trump’s attacks on Obama have been more frequent in the weeks preceding the election.

Only last week, he lashed out at the commander-in-chief for using Superstorm Sandy to garner more votes and essentially buy the election.

The billionaire’s grudge hasn’t gone unnoticed by the president. 

During a recent appearance on The Tonight Show With Jay Leno, Obama quipped that their rivalry began when the two were growing up in Kenya.

‘We had constant run-ins on the soccer field, he wasn’t that good,’ Obama told the NBC late-night host.

Obama said on Leno that the two have never actually met.

During a campaign stop in swing state New Hampshire last month, Obama again joked about his birth certificate.

He joked that Mitt Romney had made it too expensive for him to get a birth certificate.

‘He raised fees to get a birth certificate which would have been expensive for me,’ the president said. 

The joke was met with laughter and cheers, and was a veiled reference to so-called ‘birthers’ who doubt he was born in America and question the authenticity of his Hawaiian birth certificate.
