TAMPA, Fla. (MCT) — Presenting himself as a turnaround artist for economically troubled times, Mitt Romney accepted his party’s presidential nomination Thursday night with a forceful promise to lead America to renewed prosperity after years of dashed expectations.

The Republican challenger, standing before a packed arena in the swing state of Florida, repeatedly invoked President BarackObama’s 2008 slogan of hope and change, saying that his November opponent had instead delivered disappointment and division.
