Clinton presses for debate before New Hampshire primary

There will be "no formal agenda" for Wednesday morning's Oval Office meeting, White House spokesman Josh Earnest said in a statement, adding that the meeting was first discussed in December.

The poll, which was conducted before this week's Democratic forum and has a margin of error of +/-4 points, shows Sanders leading 49 to 45, with former Maryland Gov. Martin O'Malley registering just 4 percent.

Sanders said he and Clinton are in a "nip-and-tuck" race in Iowa but predicted that, with a success, he would begin to see more support from establishment Democrats who have coalesced around the former secretary of state's candidacy. I've [said] for, you know, for a long time, that I'd be happy to have more debates, and I hope we can get this done. The former first lady has avoided hitting Sanders directly for much of the week, however, instead choosing to tout herself and her policies and only subtly knock the senator who is challenging her in Iowa and New Hampshire.

"The DNC has said this would be an unsanctioned debate so we would not want to jeopardize our ability to participate in future debates", Sanders' campaign manager Jeff Weaver said. Obama has met previously with Clinton.

Last time, in 2008, it was Barack Obama. He said he believed the president and the vice president have been "fair and even handed".

"I think the American people, working people, young people, want to see real movement in this country", he said.

Although Clinton does post many of her plans on the White House and her campaign has detailed how he plans to pay for them, so, too, has Sanders.

Sanders-Obama meeting took place only days ahead of the crucial Iowa Caucus.

"It was mid-summer before Sanders had people on the ground", said Matt Tapscott, Democratic chairman of Winneshiek County, where Decorah is located.

While Clinton has stepped up the attacks on Sanders in the last two weeks, she has vacillated between knocking the Vermont senator, who is running close with Clinton in Iowa, and pushing her own platform and message.

"A dollar and 61 cents a week to make sure when you have a baby, you can stay home with that baby and not be forced back to work", Sanders said.

"What the president has tried to do, what Vice President Biden has tried to do, is to be as evenhanded as they can be", Sanders said.

"I would like the chairman of the party and the campaigns to agree that we can debate in New Hampshire next week", Clinton added.

"We are grateful that the Union Leader and NBC have heard the voices of New Hampshire voters who have advocated loud and clear for a final debate since the summer", the group New Hampshire Debates wrote in a letter to candidates.

The president brushed off analogies between the campaigns in the Politico interview, instead portraying Sanders more as a gadfly than a serious politician.
