The president’s speech to around 20,000 democrats at the Time Warner Cable arena in the city of Charlotte, North Carolina focused on economic recovery and the threat of his rival of the Republican party Mitt Romney.

“You didn’t elect me to tell you what you wanted to hear. You elected me to tell you the truth. And the truth is it will take more than a few years for us to solve challenges that have built up over decades.”

Obama’s official acceptance to accept the Democrat party’s nominations to face Romney in the fight for his next 4 years in the White House was met with “deafening applause from delegates.” according to The Guardian.

During his attack on what he saw as Mitt Romney’s unsuitability for the job, he referred to Britain as the United State’s ‘closest ally’ and recalled Romney’s recent pre-Olympics gaffe during his visit to London, saying “You might not be ready for diplomacy with Beijing if you can’t visit the Olympics without insulting our closest ally.”

Returning to the theme of ‘change’ that proved popular during his campaign for president four years ago, Obama said “If you turn away now – if you buy into the cynicism that the change we fought for isn’t possible … well, change will not happen.”

“Tonight President Obama laid out the choice in this election, making the case for more of the same policies that haven’t worked for the past four years.” said Romney’s campaign manager Matt Rhoades. Romney had told reporters earlier in the day that he would not be watching the president’s speech.
