(CNN) – One day after becoming the presumptive Democratic vice presidential nominee, Delaware Senator Joe Biden sent a video message to Barack Obama’s supporters introducing himself — and hinting at his appeal to key voting blocs the Illinois senator has long worked to win over.
“There’s never been anything like it,” Biden says into the camera, seated with an American flag over his shoulder. “This campaign has already accomplished so many amazing things. For one, it’s cut through the old-school partisanship that currently plagues Washington.”
Before briefly summarizing his work in the Senate, Biden first says that he comes from “a big Catholic family with a strong tradition of service.” Obama has had some trouble with Catholic Democrats, most flocked to Hillary Clinton during the primaries.
Biden also touches on his penchant for blunt talk that has landed him in some trouble in the past.
“I know I’m known for speaking my mind, hopefully clearly and strongly,” says Biden seriously, “but I do it on behalf of the middle class.”
He closes by asking people to sign up as volunteers for the campaign.
“My plan quite frankly is to roll up my sleeves and do what you’ve been doing. Make the phone calls, knock on the doors. Talk to new voters and new supporters face to face.”
Though the campaign has already rolled out a new Obama/Biden logo, the video finishes with an “Obama ’08” graphic.
