Vice President Biden on Friday diagnosed GOP vice presidential nominee Paul RyanPaul Davis RyanLaura Ingraham: George Will is ‘sad and petty’ for urging votes against GOP Seth Rogen: I told Paul Ryan I hate his policies in front of his kids George Will: Vote against GOP in midterms MORE with the same form of political amnesia that the president has identified with Mitt Romney.

"Romnesia," Biden said, speaking at a campaign event at the University of Wisconsin-Oshkosh. "By the way, it is contagious: Poor Paul caught it. The guy who was known for saying exactly what he means."

President Obama began using the "Romnesia" term last Friday in attacks characterizing his GOP opponent as a flip-flopper.

"He's forgetting what his own positions are, and he's betting you would too," Obama said of Romney at a campaign stop in Virginia. "He's backtracking and sidestepping. We've got to name this condition he's going through. I think it's called 'Romnesia.' I think that's what he's going through."

Romney's campaign pushed back by calling the "Romnesia" charge another example of the president running a "small" campaign by basing his attacks on jokes.

But Biden extended the description to Ryan this week, saying that the Wisconsin congressman has forgotten what is in his own budget proposal. That budget, proposed by Ryan as the House Budget Committee chairman and adopted by House Republicans, is not the same as Romney's, but the GOP nominee has said they are on the same page.

Biden referred back to the three recent presidential debates, as well as his own vice presidential debate with Ryan, saying the debates have exposed some of the stark differences between the Democratic and Republican presidential tickets.

"As the president pointed out, these debates have exposed that Gov. Romney and Paul Ryan have a very different foreign policy than we do; it's right out of the Cold War," he said. 

"And social policy? I guess they got caught up in 'Mad Men,' I don't know, but it's right out of the '50s," he continued, citing the hit AMC show set in an early 1960s workplace.

Planned Parenthood President Cecile Richards has used the "Mad Men" attack in the past, notably in her speech at the Democratic National Convention last month, where she said Romney's plan to eliminate funding from Planned Parenthood made her feel like "we woke up in a bad episode of 'Mad Men.'”

The Romney campaign responded to Biden by saying his criticism doesn't help voters.

“Vice President Biden today failed to offer an agenda to help the struggling middle class," said Romney spokesman Ryan Williams. "There is a big choice in this election to change the direction of the country. Americans can’t afford four more years of President Obama’s policies that have led to 23 million Americans struggling for work, anemic growth, and out of control spending. Mitt Romney and Paul Ryan have a Plan for a Stronger Middle Class that will deliver a real recovery by cutting spending, increasing energy production, and making America the best place in the world to start and grow a business.”
