The Obama camp says that could be the first day Obama and Biden campaign together --and you know the media will be wanting to read the body language and listen for the gaffes and all that fun stuff.
CNN: Barack Obama campaign sources told CNN's Gloria Borger and Jessica Yellin that Obama and his running mate, Joe Biden, will have their first post-convention joint rally Friday, likely in Pennsylvania.
That's the day after Obama gives his presidential nomination acceptance speech, wrapping up the Democratic National Convention in Denver.
And it's also the same day that John McCain is expected to hold a rally in Dayton, Ohio. The conventional wisdom is that the Ohio event could be the first public appearance of McCain and his yet to-be-named running mate.
Obama sources say the joint appearance by Obama and Biden could be a good way to counter-program the Republicans.
