New NBC News/WSJ/Marist polls from Florida, Ohio and Virginia show the presidential race tightening in two of the three states.
In Florida, the poll shows President Obama statistically tied with Republican Mitt Romney at 47 percent to 46 percent, down from a 49 percent to 45 percent lead in a mid-September poll. In Virginia, Obama is at 48 percent to Romney's 46 percent, compared to another 49 percent to 45 percent last month.
Obama maintains his lead in Ohio, 51 percent to 43 percent.
"The polling in September was right after the conventions," Marist pollster Lee Miringoff, told NBC News. "We may be seeing a dissipation in some of [Obama's] post-convention bounce."
