Obamas, Bidens, to visit New Hampshire after convention

This should banish any doubt that New Hampshire matters in November: President Barack Obama, First Lady Michelle Obama, Vice President Joe Biden and Dr Jill Biden will all attend a campaign rally in the Granite State the day after the Democratic convention, next Friday.

It's unusual for both couples to attend the same campaign event. The president will accept the Democratic nomination on Thursday night in Charlotte, N.C.

Obama will go to Florida the following Saturday and Sunday, while Biden will stump for votes in Ohio.
