Washington (CNN) - Vice President Joe Biden says he's "so tired about hearing about the demise of the Democratic Party."
Giving a pep talk Thursday to Democratic Party officials to go on offense as the 2014 midterm election season heats up, the vice president went on to say that "my central message to you is look: I think we should not apologize for a single thing."

Biden's comments came as he spoke to state party chairs, who are gathered in the nation's capital for the Democratic National Committee's Winter Meeting. The vice president said that Democrats need to lay out to voters that "this is who we are. This is what we stand for. This is what we'll do," adding that "if we run on what we believe. If we run on our value set, which happens to be totally consistent with where the American people think we should be on this substance set of issues, we will win."
Biden, who's mulling another bid for president in the next race for the White House, cautioned against looking ahead to the next election, saying that "everybody wants to talk about 2016. That's lifetimes away."
The vice president repeated his pledge, which he gave in an interview with CNN earlier this month, that he's committed to campaigning for fellow Democrats this year, saying "I think I’m signed up for more than 120 races."
Biden painted the GOP as a party of pessimists, and as he's mentioned in the past, Biden said "there is no Republican Party,” citing the four separate responses to President Barack Obama's State of the Union address.
Democrats may face challenges this November. The traditional lower voter turnout during midterm elections often favors the GOP over the Democrats. And Obama's low approval ratings are also working against the Democrats.
Democrats hold a 55-45 majority in the Senate (53 Democrats and two independents who caucus with the party), but are defending 21 of the 36 seats up in November, with half of those Democratic-held seats located in red or purple states.
In the House, Democrats need to pick up 17 GOP-held seats needed to win back control of the Republican-led chamber, a feat political handicappers say is unlikely considering the shrinking number of competitive congressional districts.
