Washington (CNN) - A new poll indicates that Senate Majority Leader Harry Reid, D-Nevada, continues to trail two potential Republican rivals, less than one year before the 2010 elections.
Former Nevada Republican Party Chair Sue Lowden holds a 10-point lead over Reid, while businessman Danny Tarkanian has a six-point advantage over the Democratic senator, according to the Mason-Dixon Polling & Research survey conducted on behalf of the Las Vegas Review-Journal.
The poll was published in Friday's newspaper.
The survey also indicates that Reid's favorable/unfavorable rating was upside down: 38 percent favorable, 49 percent unfavorable, with 13 percent not expressing an opinion.
This is the third Mason-Dixon poll in five months that suggests the Democratic senator in trouble of winning re-election to a fifth term. Reid, who was first elected to the Senate in 1986, has pledged to spend up to $25 million to stay in office.
The Las Vegas Review-Journal/Mason Dixon poll was conducted November 30-December 2, with 625 registered voters in Nevada questioned by telephone. The survey's sampling error is plus or minus 4 percentage points.
