Howard Dean will bring his bus tour to Raleigh, Greensboro and
Charlotte on Friday.
He's been touring across the South, hoping to help Obama swing some reliably Republican states into his column. Obama has predicted he can win some Southern states, in part by increasing the participation of blacks and young voters.
He has been airing television ads in Georgia, North Carolina and Virginia.
Dean began his tour in the Texas hometown of President Bush. He will continue his tour with a visit to Georgia on Saturday.
