(CNN) – Senate Majority Leader Harry Reid remains extremely vulnerable to a Republican challenger this November, according to a new poll.
A Mason Dixon/Las Vegas Review-Journal survey of registered Nevada voters indicates Reid losing to the leading two Republican challengers by double digits. Against state GOP chairwoman Sue Lowden, Reid faces a 52-39 percent deficit while the Nevada Democrat is down 51-40 percent against businessman Danny Tarkanian.
But Reid's fortunes may be boosted by the presence of potential Tea Party-backed candidate John Ashijian, a businessman in Las Vegas who has no political experience. According to the poll, Reid would win a three-way race that included a Tea Party candidate, garnering 36 percent of the vote compared to 32 percent for a generic Republican. The Tea Party candidate registered 18 percent.
Yet Reid's overall approval rating remains dismal, with only a third of Nevada voters giving the Senate majority leader positive reviews.
The results come after President Obama hit the campaign trail for Reid in Las Vegas, holding a town-hall meeting at a local high school and delivering a speech before the Las Vegas Chamber of Commerce. The president also appeared at a high-powered fundraiser for the Democratic National Committee. But three-quarters of those polled said the president's recent appearance did not affect their view of Reid, who's fighting for 5th term in the Senate.
When it comes to the Republican primary, Lowden holds a commanding 47-29 percent lead over Tarkananian while conservative candidate Sharron Angle registers 8 percent.
The Mason Dixon/Las Vegas-Review-Journal poll questioned 625 registered voters by telephone from February 22-24 and carries an overall sampling error of 4 percentage points.
