Hempstead, New York:
Mitt Romney says he differs from fellow Republican George W. Bush on energy policy, China and deficits. President Barack Obama says the biggest difference is that his GOP rival is more extreme on social issues than Mr Bush.
A voter during Tuesday's town hall-style debate asked Mr Romney how he was different than Mr Bush, who left office deeply unpopular. Mr Romney says that he would govern under different conditions that would allow him to make North America energy independent from Arab and Venezuelan oil. He also says he would crack down on China's currency manipulation and cut the deficit by increasing trade.
Mr Obama was ready with a quick retort. He says Mr Romney, unlike Mr Bush, would cut funding to Planned Parenthood and that Romney would pursue a more stringent immigration policy than Bush did.
