A new poll from Magellan Strategies finds Sen. Mary Landrieu (D-LA) leading the field in her fight to win re-election.

But Landrieu falls short of the 50 percent support she would need to avoid a runoff in the race. The Magellan Strategies survey found Landrieu gains a plurality of the support in the field with 39.3 percent of the 600 voters surveyed, according to The Hill.

Meanwhile, Rep. Bill Cassidy (R-LA), the lead Republican candidate in the race, gets 26.3 percent. The other two candidates in the race, Republican Paul Hollis and tea party favorite Rob Maness (R) both only get 3 percent support each.

Louisiana’s Senate race is an open primary often referred to as a “jungle primary” meaning that all the candidates run in the same primary no matter their party affiliation. The primary is held on Nov. 4 and if any candidate wins 50 percent of the vote the win the seat. If no candidate wins 50 percent the top two vote-getters go to a runoff held on December 6.

The poll was conducted among 600 registered voters between March 24 and March 26. It had a margin of error of plus or minus 4.1 percentage points. It was commissioned by conservative businessman Lane Grisby.
