Gallup finds that 50 percent of Americans of those in poverty consider themselves politically independent — a far higher percentage than those who identify as Democrats or Republicans:

The data is from 2011 — the most recent year for the official poverty threshold — but Gallup points out that partisanship levels haven't changed much in the first half of 2012.

Political independents in poverty are more likely to lean Democratic and approve of Obama, Gallup says. But there's a lot to suggest that they're far more politically disengaged. Gallup explains, "those in poverty were almost twice as likely as those not in poverty to have no opinion of the job the president was doing."

So despite the hundreds of millions being spent on the election to court swing voters, the political independents in poverty may stay on the sidelines.

*Correction: An earlier version of this post stated that half of the politically independent were in poverty. The poll shows that half of those in poverty are politically independent.
