Upside to potential storm for GOP convention?

(CBS News) Republican officials are preparing for the possibility that Tropical Storm Isaac could interrupt the Republican National Convention next week. Already, officials plan on officially nominating Mitt Romney for president on Monday in Tampa, two days earlier than expected, in part because of the storm.

One of the advantages of rearranging the convention schedule is the possibility of more coverage of the speech that Mitt Romney's wife Ann is currently set to deliver on Monday, CBS News political director John Dickerson said Friday on "CBS This Morning."

"If everything was moved to another day, perhaps they could get bigger coverage of Ann Romney," Dickerson said.

Broadcast networks will not be covering Monday night convention events, to the detriment of the Romney campaign, which thinks Ann Romney can help bring a personal touch to the GOP ticket.

"The challenge for Mitt Romney is to reintroduce himself to voters," Dickerson said. "He has what pollsters call a 'likability problem,' people just don't know him."
