Reps. Charles Boustany Jr. (R-La.) and Jeff Landry (R-La.) are heading to a runoff after both failed to reach 50 percent of the vote in their all-party election.

Boustany leads Landry by 45 to 30 percent with all precincts reporting.

Louisiana lost a House seat in redistricting because of slow population growth. Boustany's allies in the statehouse made sure that Landry's political base was shattered and put in multiple districts, but the Tea Party freshman ran a hard race and was helped by a Democrat deciding to run and split the vote multiple ways. Boustany's goal was to win the race in the first round of voting, while Landry's was to make it to a runoff.

While Boustany has a wide lead in the first round of voting, the second round could look much different. A December runoff election will likely only draw the most hardcore voters, and Landry has strong Tea Party support, which could give him a big boost against the long-time congressman, who is close with House Speaker John Boehner (R-Ohio).
