Republican presidential candidate Mitt Romney has crowned a string of Super Tuesday victories with a wafer-thin win in the swing state of Ohio.
Addressing supporters in his home state of Massachusetts, before all the results were in, he said he was confident of victory "all the way to the White House".
Mr Romney also won Idaho, Vermont, Virginia and Alaska.
