Rep. Julia Letlow and Jamie Davis head to final round for U.S. Senate

Catch up quick: Party primaries in May ended with 45% of the vote for Letlow and 28% for Fleming, according to secretary of state data. That vote knocked Cassidy out of the race and seemed to set Letlow up for an easy victory.

• But Fleming's supporters rallied to give Letlow a tighter-than-expected race. She ended Saturday's primary runoff with 57% of the vote to Fleming's 43%, according to secretary of state data.

Between the lines: President Trump, who endorsed Letlow in January, spent the campaign's final days aiming to energize Louisiana voters on her behalf, including with last-minute text messages and another endorsement.

• Letlow thanked Trump at her election night party in Baton Rouge, the AP reports, calling him "the greatest president this country has ever had."

The intrigue: There are several months to go until November's general election, but Democrats don't anticipate flipping the Senate seat, the AP has reported.

Some New Orleans-area voters also made decisions on two other Republican primaries, sending additional candidates to November's general election:

• State Rep. Stephanie Hilferty will vie for the Public Service Commission District 1 seat, along with Democrat Connie Norris and Chris Justin, a no-party candidate, The Times-Picayune reports.
• Joseph Cao takes aim at the Board of Elementary and Secondary Education District 1 seat. Democrat Angela Hershey, who secured her party nomination unopposed, according to the Louisiana Illuminator, will also be on the ballot.

What's next: The general election is slated for Nov. 3, and it'll include open primaries for the delayed U.S. House race.

• Early voting begins Oct. 20.
