Poll: Obama slips to two-point lead in Nevada

President Obama is holding to a narrow two-point lead in Nevada, although Mitt Romney has seen his prospects improve after naming Paul Ryan as his running mate, according to a poll released Wednesday.

The survey by the Las Vegas Review Journal showed President Obama and Vice President Biden edging the Romney-Ryan ticket 47 to 45 percent. That's the closest Romney has been to the president since an NBC News poll in May.

But while Romney edged closer to the president overall, Nevada voters who were polled are split on whether the addition of Ryan hurts or helps the ticket. While 28 percent said the Wisconsin lawmaker's selection made them more likely to pick Romney, 29 percent said his choice made them more inclined to vote for the president. About 42 percent said that the new Republican running mate would not influence their eventual choice.

Similarly, 48 percent of Republicans said they were more likely to vote for Romney after hearing about the pick, while 48 percent of Democrats said the addition of the Wisconsin lawmaker would encourage them to come out for Obama.

Voters were also evenly split on Ryan's Medicare plan; while seven in 10 said they were "familiar with Paul Ryan's thinking on Medicare," 48 percent said they supported his plan and 47 percent said they opposed it.

Nevada's six electoral votes could play a deciding role in November's election; the president is hoping that the Hispanic population in the state can help him carry it, while Romney is leaning on the Mormon vote and Republicans energized from his heavy campaigning there during the primaries.

The poll carries a margin of error of 3.4 percent.
