(CNN) -- As the GOP struggles to find a candidate to challenge Senate Majority Leader Harry Reid, a new poll out Tuesday suggests the Nevada Democrat is extremely vulnerable 18 months before Election Day.According to the new survey conducted by Mason-Dixon for the Las Vegas Review-Journal, only about a third of the state's voters said they would vote to re-elect Reid to a fifth Senate term, while 45 percent said they would definitely vote for another candidate. An additional 17 percent of voters say they would consider voting to oust Reid.
The poll also suggested Reid's approval rating back home stands at a meager 38 percent, while about half of Nevada voters hold a negative view toward the Senate Majority leader.
Reid has long been a divisive figure in his home state, especially since ascending to the position of majority leader in 2006. But even though there are few more valuable Democratic targets in the Senate, the GOP has yet to find a credible candidate willing to challenge Reid, known for his take-no-prisoners style back at home.
Meanwhile Reid is raising campaign cash at an impressive clip, amassing more than $2 million in his war chest during the first quarter of the year.
Jim Manley, a spokesman for Reid, brushed aside the poll results, saying, "Sen. Reid has never put a lot of weight in polls.
"Polls by the Review-Journal are consistently out of line with other polls," Manley also said. "The primary number he's worried about is Nevada's 10.4% unemployment rate and that's why he's focused on fixing the economy and creating jobs in Nevada."
The survey interviewed 625 Nevada voters and carries a margin of error of plus or minus 4 percent.
