In an election that was supposed to be about jobs, jobs and jobs, the unemployed vote appears to be a dead heat.

In an exclusive look at how the unemployed will likely vote, CNBC found 26% of the public report either they or someone in their household has lost a job in the past four years.

But this group splits 48% to 48% in their presidential choice, similar to the broader population, which splits 48% to 47% for President Obama.

If the respondent themself was unemployed, the break is 50% for Obama vs. 45% for Republican challenger Mitt Romney. If only a person in the household lost a job (not the individual respondent), the split is 51% for Romney vs. 48% for Obama.

With a 7.9% unemployment rate in October, President Obama stands for reelection with the highest jobless rate of any president in the post-war era.

Of the four other incumbents who ran with unemployment rates above 7% — Gerald Ford, Jimmy Carter, GHW Bush and Ronald Reagan — only Reagan won back the White House.

Significantly, while the unemployment rate under Reagan was 7.4% in the October before the election, it had fallen 1.4 percentage points in the prior 12 months.

Under Obama, unemployment has fallen by 1 percentage point in the past year.

The data raises several questions that can only be answered by actual election results, including whether the change in the unemployment rate is more or equally important than the level of joblessness.

It could be that the positive momentum in the rate, added to the power of the incumbency, is sufficient to keep Obama in the White House. It could equally be that the high level of unemployment is a key factor in winning Romney the job.

However, the split support among the unemployed suggests Romney was not overwhelmingly successful in winning the support of those who have personally experienced joblessness. That could be because his message on jobs was not strong enough or because other factors — race, political leaning and especially income level — were more important.

The demographics of the unemployed skew slightly less white than the broader population. But it's hard to attribute the split among the unemployed to ethnicity.

White voters overall break 57% to 38% for Romney. White voters who have experienced unemployment break 57% to 42% for Romney, which is not a statistically meaningful difference. But it shows that Romney was not successful in gaining significantly more support among Whites who have experienced unemployment compared to those who have not.

Of course, the actual election results will almost certainly differ significantly from the polls and it could turn out that unemployment is the front-burner issue it was cracked up to be. Indeed, other polls have shown that for the broader voting population, jobs is a key factor in presidential choice.
