NBC polls: Obama edges Romney in three key battleground states
By Mark Murray, Senior Political Editor, NBC News
President Barack Obama holds a narrow advantage over presumptive Republican nominee Mitt Romney in three of the most pivotal presidential battleground states -- Florida, Ohio and Virginia -- according to new NBC-Marist polls.
But in each of these states, Obama's share of the vote is below the 50 percent threshold usually considered safe haven for an incumbent president, and Romney has narrowed the margin in these three battlegrounds since earlier this year.
In Florida and Virginia, Obama leads Romney by an identical four-point margin, 48 percent to 44 percent, among registered voters, including those who are undecided but leaning toward a particular candidate.
