Speaking for no more than five minutes, former Massachusetts governor Mitt Romney used his concession speech to thank his family, staffers and supporters and to urge an end to partisan gridlock. 

"At a time like this we can't risk partisan bickering and political posturing," he said. "Our leaders have to reach across the aisle to do critical work."

Romney thanked his wife (saying "she would have been a wonderful first lady,") his sons, his campaign staff, his volunteers and his running mate, Rep. Paul Ryan (R-Wis.).

"Paul and I have left everything on the field. We have given our all to this campaign. I so wish I had been able to fulfill your hopes to lead the country in a different direction, but the nation chose another leader," Romney said. "Ann and I join with you to earnestly pray for him and this great nation."

He ended with a "You guys are the best" and a "Thanks, guys" to the crowd.
