(CNN) - Voter turnout could be crucial in the battle between Senate Majority Leader Harry Reid and his Republican challenger, Sharron Angle, and a new poll indicates that Republican voters in the state are more energized than their Democratic counterparts.
According to a Reuters/Ipsos survey of Nevada voters released Tuesday, 81 percent of Republicans say they are certain to vote on November 2, 17 points higher than the 64 percent of Democrats who say they'll vote in the midterm elections.
The poll indicates that Reid leads Angle 48 to 44 percent among likely voters. Among the larger poll of registered voters, Reid holds a 52 to 36 percent advantage.
"He (Reid) is well within her striking distance," says Ipsos pollster Julia Clark. "I think this one will go down to the wire and it will absolutely depend on turnout."
A Mason-Dixon survey conducted for the Las Vegas Review-Journal and KLAS-TV released last Friday indicated that 43 percent of Nevada voters support Reid with 42 percent backing Angle. Reid led Angle by 7 points in the previous Mason-Dixon poll, which was conducted two weeks earlier.
Reid is facing a difficult re-election as he bids this year for a fifth term in the Senate. Nevada has the highest unemployment level of any state in the nation and some of President Barack Obama's policies that Reid helped guide through the Senate are unpopular in the state.
More than seven out of ten questioned in the Reuters/Ipsos poll say that Nevada's on the wrong track.
Angle beat 12 other candidates in the June 8 GOP primary to capture her party's Senate nomination. The former Nevada state lawmaker enjoys strong support from many in the Tea Party movement.
According to the poll, one out of four Republican voters said they were more inclined to support Angle because she enjoys backing by Tea Party groups, with seven percent saying they are less likely to support Angle because of her Tea Party backing.
The survey also indicates that more than six in ten Nevada voters support their state adopting an immigration law similar to the new controversial measure adopted in Arizona.
The Reuters/Ipsos poll was conducted July 30-August 1, with 600 Nevada voters questioned by telephone. The survey's overall sampling error is plus or minus four percentage points.
