"Last night, in a cell phone text message that was quickly followed by an e-mail linking back to a new page on his Web site -- my.barackobama.com/vp -- aides to Sen. Barack Obama's (D-Ill.) campaign wrote: "Barack will announce his VP candidate choice through txt message between now & the Conv. Tell everyone to text VP to 62262 to be the first to know! Please forward."
Meanwhile, John McCain is still trying to get a handle on the Internets:
"I am learning to get online myself, and I will have that down fairly soon, getting on myself."
