According to a survey conducted by Harper Polling, incumbent Sen. Mary Landrieu would lose to Republican Congressman Bill Cassidy in a runoff.
"It appears that Landrieu is in for the race of her life," says UL-Lafayette Political Science Professor Pearson Cross. "Perhaps for the first time she is entering the home stretch as a definite underdog."
The Republican group American Crossroads paid for the survey. In a primary, 40% of those polled support Landrieu and 35% support Cassidy while Republicans Rob Maness and Rep. Paul Hollis got four and three percent respectively.
But Cassidy would beat Landrieu 47-43 in a runoff.
Cross says the Democratic Senator faces a tough road.
"She was well ahead of her last opponent, John Kennedy, at this stage, polling above 50 or at least close to 50%," Cross said. "Now she's polling quite a bit below that and in the head up race is behind."
18% of respondents said they were undecided for the primary and 10% said the same in a runoff scenario.
Cross says this poll indicates there is support for candidates other than Cassidy and Landrieu, but when you put them together the votes move to Cassidy.
He says things could change if the GOP decides to endorse a candidate.
"If they were to do so, it would probably make Cassidy look even more formidable," said Cross.
