President Obama Calls on Young Voters; Turnout at Polls Expected to be Robust

President Obama, who spent all weekend in a multi-state campaign swing to help boost fledgling Democratic candidates, knows Democrats will have to make adjustments in their agenda going forward, Kaine said on "GMA."

"The president is upbeat about the rallies and how they've gone and the energy," Kaine said. "He has a good sense of perspective about the challenge of the midterm elections and about the need to make corrections. You'll see those play out over the course of the new few weeks."

An ABC News/Washington Post poll shows that nearly six in 10 registered voters have an unfavorable opinion of Democratic Speaker of the House Nancy Pelosi. But GOP Minority Leader John Boehner, whose name has been circulating as potential Speaker should Republicans regain control of the House, is also more disliked than liked by a 35-to-21 percent margin.

But Kaine also admonished Democrats who have separated themselves from the party's agenda.

"Democrats need to be proud of the president, proud of their accomplishments and proud of the party," he said. "I think Democrats need to do that a little bit more."
