Incumbent Republican David Vitter has an even more commanding lead this month over his top Democratic challenger in Louisiana's race for the U.S. Senate.
The latest Rasmussen Reports telephone survey of likely voters in the state shows Vitter leading Democratic Congressman Charlie Melancon 57% to 33%. Just three percent (3%) would opt for some other candidate, while seven percent (7%) are undecided.
In January, Vitter led Melancon 53% to 35%. Melancon also trailed Secretary of State Jay Dardenne, who was considering challenging Vitter for the GOP Senate nomination, by a 53% to 31% margin in that poll.
Vitter received less than 50% against Melancon in October. Incumbents who earn less than 50% of the vote at this stage of the campaign are considered vulnerable.
Dardenne has since announced that he will not run against Vitter.
