Los Angeles (CNN) - A second straight poll suggests that a candidate backed by a national Tea Party organization is now in the lead in the battle for Nevada's Republican Senate nomination.
With two days to go until Nevada's primary, a new Mason-Dixon survey conducted for the Las Vegas Review-Journal indicates that 32 percent of likely GOP primary voters back Sharron Angle. The former member of the Nevada Assembly has won endorsements in recent months from many conservative organizations, including significant financial backing from the Tea Party Express, a national Tea Party group best known for running three cross country bus caravans, and the Club for Growth, a fiscally conservative organization.
Angle has aggressively touted her connection to Tea Party activists, calling the movement "a tsunami of conservatism across this country."
According to the poll, which was released Sunday, 24 percent support Las Vegas businessman and former University of Nevada Las Vegas basketball star Danny Tarkanian, with 23 percent pulling for businesswoman and former Nevada GOP party chairwoman Sue Lowden. The remaining candidates in the field of a 13 bidding for the Republican Senate nomination are in single digits in the survey. Thirteen percent of people questioned in the poll remain undecided. The percentage of people unsure about their vote is up five points from a Mason Dixon poll released a week ago.
A Suffolk University Political Research Center survey released Thursday indicated that 33 percent of state GOP voters back Angle in Tuesday's primary, with Tarkanian at 26 percent and Lowden at 25 percent.
Angle appears to be surging. A Mason-Dixon poll conducted in early April indicated Angle was a distant third, far behind Lowden and Tarkanian. But according to a Mason Dixon survey conducted last month, Angle had jumped into second place, trailing Lowden by five points.
"Angle is the favorite at this point, but I wouldn't say it's a done deal," Mason-Dixon pollster Brad Coker tells the Las Vegas Review-Journal. "She's got the momentum, but there's still 13 percent on the table."
Lowden appears to have suffered from a much publicized gaffe. She suggested at a town hall meeting in rural Nevada that people could barter for medical care, recalling that some even traded chickens for a doctor's services in the old days. The comments fueled sarcasm and criticism of her and her campaign.
The winner of Tuesday's Republican primary will take on presumptive Democratic nominee, Senate Majority Leader Harry Reid, who's battling for a fifth term.
The survey indicates that among registered voters, Tarkanian leads Reid 46 to 39 percent in a hypothetical general election matchup, with Angle edging Reid 44 percent to 41 percent and Reid up a point over Lowden, 42 percent to 41 percent.
The Mason-Dixon poll for the Las Vegas Review-Journal was conducted June 1-3, with 625 Nevada registered voters questioned by telephone. The survey's overall sampling error was plus or minus four percentage points. The poll included a survey of 500 likely Nevada GOP primary voters, with a sampling error of plus or minus 4.5 percentage points.
