Mitt Romney accepted his Republican Party's presidential nomination on Thursday night, and promised that he would do everything to set the economic conditions right that Barack Obama couldn't do.

Romney said he would rescue the struggling U. S. economy and create new jobs. He made the promise in the most important speech of his political career as the Republican National Convention concluded in Florida.

After accepting Republican Party's presidential nomination on the final night of the convention in Tampa, the former Massachusetts governor urged voters of the country to use their disappointment of the past four years in supporting him so that the promise of America could be restored.

He also criticized President Obama for his alleged failure in delivering his promise. He said Obama's policies depressed the economy and creation of jobs. He added that Obama raised taxes, which hurt business and led to job losses.

He also criticized the president for alleged assault on coal & gas oil, which forced the companies to send energy and manufacturing jobs to foreign countries like China.

Speaking on the topic, he added, "And let me make this very clear - unlike President Obama, I will not raise taxes on the middle class. My promise... is to help you and your family."

After trailing for several months, Mr. Romney has recently drawn in national polls with Mr. Obama.
