NBC's Domenico Montanaro talks about the decision made by the Emily's List group to start a campaign to place a woman in the White House. The group's efforts include a new ad with an obvious message towards Hillary Clinton.

With former Secretary of State Hillary Clinton waiting in the wings, a prominent Democratic group launched an effort Thursday to pave the way for electing America's first woman president.

Marshaling new polling data of voters in battleground states, the Democratic women's group EMILY's List said Americans fully believe the country is ready to elect a woman as president, pointing to results showing almost three in four Americans "expect" the nation to elect a woman as president in 2016.

The initiative, dubbed "Madam President," comes well before the next presidential election has even begun to take shape, but has clear implications for Clinton, Democrats' favorite right now to carry the party's banner.

The group EMILY's List, which supports the political advancement of women, is launching a new campaign to put a woman in the White House. Jess McIntosh discusses.

"There is one name that seems to be getting mentioned more than others," said Stephanie Schriock, the president of EMILY's List, which supported Clinton during her 2008 bid for the Democratic nomination. "We do not know if Hillary is going to run — but we're hopeful that she may."

So intense is the early interest in Clinton's potential candidacy that even her most benign public appearances since leaving her job as secretary of state are scrutinized for signals of her intentions. The runner-up in a bitter, drawn-out primary battle versus Barack Obama in 2008, Clinton's personal approval numbers have never been higher following her stint as the country's top diplomat.

To that end, a new national poll released separately on Thursday suggested that Clinton is the overwhelming favorite of Democrats in 2016. Sixty-five percent of Democrats said in a Quinnipiac University poll conducted at the end of last month that they would vote for Clinton in a primary; 13 percent would prefer Biden, while all other contenders register less than 5 percent.

"This is a wide open race if Sec. Clinton doesn't decide to do this," Schricok said, explaining that the EMILY's List campaign was not focused on any one particular candidate. She challenged pollsters to include other Democratic women among the field of candidates they test.

Among those candidates floated on Thursday: Minnesota Sen. Amy Klobuchar, New York Sen. Kirsten Gillibrand, Washington Gov. Christine Gregoire, Secretary of Health and Human Services Kathleen Sebelius and Secretary of Homeland Security Janet Napolitano.

The essence of Thursday's new "Madam President" campaign involves preparing Americans to elect any of those women. EMILY's List said it would launch an online ad campaign with a six-figure price tag to target women on sites like Oprah.com, BlogHer and Feministing — and traditional outlets like the New York Times or New York Magazine.

The purpose is to lay the groundwork for any of these candidates, and in a targeted way. The campaign will also involve town hall meetings in key nominating states like Iowa and New Hampshire, which could boost or bust a candidate's presidential aspirations.

But the possibility of electing a woman seems all the more real given the polling data debuted at Thursday's event, which found that 86 percent of battleground state voters believe America is ready to elect a woman president, and 72 percent of those voters expect that milestone to be reached in the next presidential election.

Getting more into the brass tacks of politics, the poll found that a well-qualified, generic Democratic woman candidate might get a slight boost versus a male, Republican opponent — "not a gigantic difference, but it could be meaningful," according to pollster Lisa Grove.

The prospect is tantalizing for a group like EMILY's List, which has dedicated itself to electing Democratic women candidates for decades now. A more established and influential group in Washington, EMILY's List joins upstarts like the group "Ready for Hillary" in putting more pressure on the former New York senator and first lady to take the plunge — again — in 2016.

"We're still in a country that has never done this," Schriock said. "So I feel the 'Madam President' campaign is really one to ignite this national conversation about how it's going to be beneficial to all Americans to see a woman in the White House."
