Former Massachusetts governor Mitt Romney accepted the Republican presidential nomination on Thursday with a prime-time pitch to voters on the final night of the party convention in Tampa, Florida.

"Mr chairman and delegates, I accept your nomination for president of the United States," Romney said. "I do so with humility, deeply moved with the trust you place in me. It's a great honor, it's an even greater responsibility, and tonight I am asking you to walk with me to a better future."
