Obama, Romney both face most narrow electoral map in recent history That leaves Romney with a very narrow path to victory, one that likely requires him to win large battlegrounds such as Florida, Virginia and Colorado along with Ohio, a swing state so critical that he is making four stops there in two days this week. Romney's advisers acknowledge that he still has work to do in Ohio. Just days ago, Romney moved five campaign workers from Pennsylvania to Ohio, one aide said. And though the Ohio race has grown more competitive - with Romney drawing within 5 percentage points of Obama, according to a new CNN/ORC International poll released Tuesday - the president still holds a lead in a state no Republican has ever won the presidency without. If the narrow electoral map for Romney remains relatively fixed, the same appears true for President Obama, whose advisers say they are committed to the handful of states they targeted months ago. When Obama appeared to hold a commanding lead across numerous states early last week, his strategists said they would not make a concerted play for some that appeared almost within reach, such as Arizona. Now that the race is closer, they say they are fortifying their existing borders, which allow him several options for getting to 270. "What you've seen is a stable map for a very long time," Jim Messina, Obama's campaign manager, said in an interview Tuesday. The result is the smallest, most rigid playing field in recent history: One that excludes 41 states. Locked up states Both campaigns agree that 36 states are not competitive this year, with 22 of them expected to vote for Romney and 14 for Obama. That number is misleading, though, because the Obama states are more populous; when tallied according to electoral votes, those states give Obama 197 electoral votes and Romney 169. Both Obama and Romney have spent the bulk of their money and attention this year in Ohio, Florida, Virginia, Iowa, Colorado, Nevada, New Hampshire, North Carolina and Wisconsin. Beyond those nine, another six are not being heavily contested but nor do the two campaigns agree that their outcome is certain. No state illustrates the narrowness of this year's playing field more than Ohio, where the candidates are spending more time than anywhere else. Even with Romney's uptick in national polls, his path remains virtually nonexistent without Ohio. He could win Florida, Virginia, Colorado and Nevada and still lose without the Buckeye State. If anything, his bounce has pushed him to redouble his efforts within the existing map rather than thinking about expanding it.
