The first spot out of the gate from the McCain camp focused on Biden - or Biden's criticism of Obama (mining sound bites from the presidential primary contest).
The first ad from Obama on Palin is more focused on McCain. They didn't have that same luxury of quotes from the primary. Had the pick been Romney, Obama would had some bubblin' crude. Oil that is. Black gold. Texas tea.
It's more like she is to in the opening salvo.
They're being careful. "Game changer" is a phrase that's been thrown out repeatedly in the first 24 hours after the selection.
Also we're seeing the two-handed approach at work. The one hand is more of a handshake. Obama and Biden's statement on Palin welcomes her to the contest. It's so cheery, in fact, it's almost like Christmas on Walton's mountain.
"We send our congratulations to Governor Sarah Palin and her family on her designation as the Republican nominee for vice president," the statement reads. "It is yet another encouraging sign that old barriers are falling in our politics. While we obviously have differences over how best to lead this country forward, Governor Palin is an admirable person and will add a compelling new voice to this campaign."
