(CNN) - With six days to go until the midterm elections, a new poll in the most high profile Senate battle in the country indicates Republican challenger Sharron Angle holds a four point advantage over Senate Majority Leader Harry Reid.
According to a CNN/Time/Opinion Research Corporation poll released Wednesday, 49 percent of likely voters in Nevada are backing Angle, who enjoys strong support from many in the Tea Party movement, with 45 percent supporting Reid, the top Democrat in the Senate who's bidding for a fifth term in the chamber. Angle's four point margin is within the poll's sampling error, making it a neck and neck race.

Two percent questioned in the poll support Scott Ashjian, who is running as a Tea Party candidate, but who is shunned by many in the grassroots conservative movement, and three percent say they are voting for none of the candidates listed, which is a ballot option in Nevada.
Other surveys released in the past two weeks also indicate a small single digit margin for Angle.
According to the CNN/Time poll, Reid leads 96 to 3 percent among Democrats, with Angle leading 82 to 10 percent among Republicans and 53 to 38 percent among independent voters.
"Reid is doing best in Clark County, home not just to Las Vegas but to his hometown of Searchlight," says CNN Polling Director Keating Holland. "He manages a virtual tie with Angle in her home territory in Washoe County, where Reno is located. But Reid is getting clobbered in the rest of the state, losing the rural areas of Nevada by more than three-to-one."
In a sign that enthusiasm for voting appears to be on the Republican side, when expanded from those likely to vote to the larger sample of all registered voters, Reid holds a 43 to 39 percent advantage over Angle, with five percent backing Ashjian and 12 percent saying they'll vote for none of the candidates.
President Barack Obama teamed up with Reid in Nevada last week. According to the poll, 39 percent of likely voters in Nevada approve of the job Obama's doing as president, with 59 percent saying they disapprove. Among all adults in the state, 44 percent approve of the job Obama's doing, with 49 percent disapproving of how he's handling his duties.
In Nevada's gubernatorial battle, the Republican nominee Brian Sandoval holds a 58 to 34 percent lead over Rory Reid, according to the survey. Six percent questioned say they're supporting neither candidate. Sandoval, a former federal district judge in Nevada, defeated Republican Gov. Jim Gibbons and three other candidates in the June GOP gubernatorial primary. Reid, a lawyer and commission chairman of Clark County, Nevada's largest, is also Sen. Reid's son.
The poll indicates that Sandoval has a more than two to one lead over Reid among independent voters.
"Rory Reid does not have his father's geographical strength," says Holland. "He loses Clark County by 12 points despite his time as a county commissioner there. He is also down by more than 20 points in the Reno area and loses the rest of the state by a six-to-one margin."
The CNN/Time/Opinion Research Corporation poll was conducted October 20-26, with 1,504 Nevada adults, including 1,286 registered voters and 773 likely voters questioned by telephone. The survey's overall sampling error is plus or minus 2.5 percentage points, with a sampling error of plus or minus 3.5 percentage points for likely voters.
