Much of the autopsy on Labour’s 2010 general election performance has focused on the "traditional" supporter and their apparent drift from the identity and values of the party over the last decade or so – especially on immigration. The Gillian Duffy demographic has become the party’s preoccupation.

However, new polling data suggests that Labour has been successful in attracting a rather different voter in the last two years – the liberal centrist.  Should the party now aggressively seek to appeal to working-class conservative support as some advocate, the liberal centrist may be repelled. These liberal centrists are, like their culturally conservative opposites, "values" voters. A populist agenda on immigration, culture and Europe may not be the one-way street that is often supposed. What’s more, an Ed Miliband coalition that doesn’t rely on such populism is one potential route to a majority for Labour.

In 2008, Barack Obama was able to win the presidency by assembling a coalition of support tapping into new sources of political energy ignited by demographic and social change. Unable to reverse the Democrats’ deficit amongst white voters or even significantly improve his vote in that demographic, he relied on Hispanic, young, and professional voters. With the obvious exception of Hispanics, the question is whether such a new coalition could be an option for Labour? A new poll hints that it could be a possibility.

Respondents were asked in the YouGov poll commissioned by Extremis Project whether they were more or less likely to vote for parties pursuing a particular agenda based loosely around populist themes such as concern about political and financial elites, nationhood, immigration and culture. The shift amongst Labour supporters from 2010 was very striking. Conservative support showed no such shift.

In 2010, Labour voters were "more likely" to vote for a party that pledged to stop immigration into the UK by 36% to 31%. That figure has now reversed with 36% to 32% "less likely" to vote for such a party. The poll asked the same question of a party pledging to reduce the "numbers of Muslims/presence of Islam in society". Again, we see a reverse. Thirty four per cent to 25% of Labour voters were "more likely" to vote for a party with such a pledge in 2010. It is now 31%-29% in favour of "less likely."

By comparison, the Conservative figure on the same question is 50%-15% in favour of "more likely", which is almost identical to the figure for its 2010 support. The overall figure is 37% to 23%. The likely explanation would appear to be Labour’s success in wooing Liberal Democrat supporters and young voters since 2010. The poll shows a clear generational divide between younger and older voters.

A new Ed Miliband coalition would combine liberal centrists, young voters, those in the public sector as well as the more traditional working and lower middle-class support who are concerned about whether the Conservatives speak for them.

The values voter Miliband seems to be attracting is more, not less liberal on immigration, more, not less accepting of other cultures, and less prone to muscular articulations of national identity. Would he really want to reverse these gains in a populist race that he would find very difficult, if not impossible, to win?

Again, the echoes of Obama’s strategy are striking. The president has embraced gay rights, the green agenda and pitches at both young and professional, college educated support through improving access to higher education (Liberal Democrats take note) and an emphasis on investment in science. He pitches towards both the Hispanic and more liberal audiences with a commitment to immigration reform: better managed borders combined with pathways to earned citizenship.

A critical aspect of this strategy is the frame. So Obama’s pitch is not open borders instead of closed borders. It’s managed immigration versus inaction. It’s not renewable energy instead of oil and gas. The frame is rather pitched around energy security and economic growth. On gay rights, a choice has been made but the articulation is around committed relationships and a contribution to society.

The issues that Miliband faces in political terms are slightly different, but the strategy of pitting pragmatism against ideology and incompetence is instructive. While the default position on immigration is anxiety and scepticism, a majority of people are pragmatic when it comes to certain migrant groups – a failure of the Conservative immigration cap will help his cause. It is to this pragmatism that Miliband could appeal to.

The same goes for Europe, green issues, and potentially even welfare as long as there is an understanding of the deep concern with the welfare state as it is. Given that the Coalition is heading in a distinctively Thatcherite direction – blue collar populism has taken over from progressive conservatism – on these issues, that leaves the pragmatic centre open to Miliband should he wish to take it.

What’s the catch? Most critically, the economy is not going away and a perceived failure of the coalition to turn things around will not be enough for people to invest their faith in Labour. A credible approach to the economy and the deficit is critical. Just as important is the leadership question. If Miliband is not seen as a convincing and competent alternative to David Cameron he will equally struggle to maintain this new-found support. Obama passed both these tests.

Further research is needed to understand how this coalition works on a seat-by-seat basis – could it be too metropolitan? Moreover, this strategy certainly doesn’t mean that Labour should not concern itself with the very serious under-currents of cultural antagonism that exist in British society as poll after poll – including the Extremis Project/YouGov poll - has demonstrated. This is real and in, many ways, frightening.

More broadly, this strategy involves a very fine balancing act. An authentic emotional engagement with nationhood and a sense of national values is critical. See Michelle Obama’s speech where she emphasised that her husband "knows the American dream because he’s lived it". Equally, it involves clawing back assumptions both within the Labour Party and the wider media establishment that these cultural issues can only be dealt with in a discordant way.

With these caveats in mind, embracing and motivating this new coalition nonetheless seems like a more natural fit for Miliband than something more traditional and conservative. Avoiding over-adjustment in addressing Labour’s electoral weaknesses in 2010 is smart politics too. Labour now needs to look forward. Crafting a workable centre-left pragmatism is sound politics. Constructing a solid policy agenda is very different set of questions. For Labour, though, an Ed Miliband coalition of voters could be available to it – and it is one that could have the potential to see it into office.
