Washington (CNN) – President Barack Obama, who took his renewed pitch to cut taxes for the middle class to Iowa Tuesday, and Republican presidential candidate Mitt Romney ratcheted up the tense back and forth over outsourcing work overseas in an appeal to those hit hardest by the economic downturn.
At its core, the debate is a fierce battle to win the support of middle class voters - especially those in battleground states.
The Obama campaign continued hammering Romney over his private equity firm, Bain Capital, which "owned companies that were pioneers in the practice of shipping work from the United States to overseas call centers and factories making computer components," according to a television advertisement released Saturday. Obama's campaign has also been forcefully pushing a Washington Post report that calls Romney's former private equity firm, Bain Capital, a "pioneer" in outsourcing jobs overseas.
The campaign has made the report a focal point of its ads against Romney, and the president frequently mentions it in his stump speeches.
