Vice-presidential candidates Joe Biden and Paul Ryan clashed over the US economy and taxes during their debate.
Mr Biden took the opportunity to address Mitt Romney's recent controversial comments that the 47% of Americans who pay no federal income tax should take responsibility for themselves.
Mr Ryan strongly defended Mr Romney's record and said:
"He is a good man, he cares about 100% of American's in this country and with respect to that quote I think the Vice President very well knows that sometimes the right words don't come out of your mouth the right way.
Some 28 million people watched last night's vice presidential debates, but much more important is next week's second Obama v Romney bout.
Independent polls following the debate showed that both men did well. With no overall winner both move on to campaign another day.
Vice President Joe Biden and Congressman Paul Ryan gave us the debate we should have enjoyed in Denver between the two main candidates.
