Biden hammered McCain Sunday for being out of touch, saying he’s “dead wrong about what we should do as a nation.”

CHARLOTTE, North Carolina (CNN) – After two days off the trail, Joe Biden ventured back out on Sunday afternoon, driving home the “Republicans just don't get it” label the Obama campaign is trying to saddle John McCain and Sarah Palin with to portray them as out of touch.

“What I want to tell you is this: John was [in 2000] and is now and has been dead wrong,” Biden said in a high school gym in Charlotte. “Dead wrong about what we should do as a nation. It doesn’t mean we can’t be friends, he’s just dead wrong. John just doesn’t get it.”

As Obama has in the last few days, Biden brought up McCain’s comments at a forum on service in New York last week when the Arizona senator said in Washington it’s easy to be “divorced” from everyday challenges.

“Yo!” Biden exclaimed, “I couldn’t have put it better myself. The McCain ticket seems divorced from the economic realities facing average American families.”

Biden zeroed in on John McCain for most of his speech but drew loud boos from the crowd at the single mention of Palin’s name when saying that the Republican ticket doesn’t feel obliged to re-train workers whose jobs have been shipped overseas.

The Delaware senator’s standard jabs at McCain on health care, energy, and the economy were all there but perhaps looking to stem a potential tide of women crossing over to vote for the ticket with a woman on it, Biden added a hit on McCain for not supporting a study to look at the pay gap between men and women.

He also went beyond simply promoting his campaign's proposals for the middle class, highlighting the "chemistry" on the Democratic ticket. Not just between himself and Obama, but between the Obama daughters and Biden's granddaugthers who – as Biden tells it – had a sleepover during the convention and became fast friends.

"I believe that's a metaphor, a metaphor for what the country is looking for," said Biden. "They're looking for a sleepover with people they like."

Monday Biden will deliver an economic speech in Michigan that an advisor is calling the “Bush 44 speech”, looking to further tie McCain’s economic policies to President Bush’s and accuse McCain of running a “dishonorable and deceptive” campaign.
