Polls: Obama up 2 points in Nevada, Romney holds same edge in New Hampshire

New polls released Tuesday show President Obama and Mitt Romney still in a tight, margin-of-error battle within key swing states, with the candidates trading 2-point leads in New Hampshire and Nevada.

Romney holds a narrow 49 to 47 percent lead in New Hampshire, having pulled even with independents and dominating the president among men and older voters.

But the president holds an identical overall lead in Nevada, dominating independents 50 to 44 percent in the state. The president also holds a commanding 57 to 43 percent lead among those who have voted early or absentee, according to the president.

While Nevada only represents six electoral votes, and the winner of New Hampshire will only capture four, the states could play a crucial role in what is expected to be a photo finish. The president has been marginally favored in both races to date; Romney has not led in a poll of Nevada since April, while the RealClearPolitics average of polls gives the president a 1.4 percent lead in Nevada.

But the ARG polls are both worse than the president's showing in other recent state-level polls in the two swing states, and indication Obama may not yet have fully halted Romney's momentum.

The polls each carried a margin of error of 4 percentage points.
