Mitt Romney is polling ahead of President Barack Obama among middle-income voters, according to Gallup. "Middle-income" is defined as voters pulling in between $36,000 and $89,999 a year.
Though Romney's edge among middle-income voters is similar to his lead among upper-income voters, in certain subgroups of middle-income voters he performs especially well. That includes middle-income independent voters, who right now prefer Romney by an eight-point margin, 48% to 40%. Obama leads among lower-income independents, and the two are tied among upper-income independents.
