(CBS News) SHAUMBURG, Ill. - Following, Mitt Romney had one word to send back to President Obama: "Enough."
"After the years of too many apologies and not enough jobs, historic drops in income and historic highs in gas prices, of a president who doesn't hesitate to use all means necessary to force Obamacare on the American public but leads from behind in world affairs," said Romney. "It's time to say these words. This word. 'Enough.'"
"We've had enough," he added.
Romney spoke to a crowd of about 300 in the outskirts of Chicago shortly after Illinois was called in his favor. With the undeniable shadow of Mr. Obama looming large in the state where the president's political career began, Romney hearkened back to where his own 2012 run for president began, New Hampshire.
"We began this movement on a small farm in New Hampshire on a sunny June day, surrounded by a small group of friends, family, and supporters," Romney said. "We shared a conviction that the America we loved was in trouble and adrift without strong leadership."
Instead of focusing on individuals he has met across the country while campaigning - he often references specific parents or workers he has come across -- he borrowed language from a speech Mr. Obama gave last week, speaking about some of America's most well known innovators. Romney, quoting the president, said: "We are inventors, we are builders, we are makers of things. We are Thomas Edison, we are the Wright Brothers... we are Steve Jobs. That's who we are. That's who we need to be right now."
"That's true," Romney continued. "But the problem is: he's still Barack Obama."
"This president is crushing the dream and the dreamers and I will make sure that finally ends," Romney added.
That element of the speech, and others, were borrowed from a similar address Romney gave yesterday at the University of Chicago. The crowd laughed when Romney mentioned that he had been at the school, where the president had once taught constitutional law. Romney argued that pedigree did not qualify Mr. Obama to be able to lead the economy.
Romney started off his remarks by saying that he had spoken to Republican Sen. Mark Kirk, who had endorsed Romney, but suffered a debilitating stroke in January. According to his campaign, Romney also spoke to Rick Santorum, who called him before he took the stage.
