So what does Nungesser get out deal? Landry’s support for Senate against Casssidy?

You're telling me I have to choose either Nungesser or Cassidy for Senate?

Easier path to re-election?

One thing that is not clear from that article is whether he is asking Landry to oppose the diversion.

That thing is getting built, and I will vote against anyone who argues otherwise.

Just curious, has Billy Nungesser ever had a real, actual job? Or has he been at the government teat his entire life?

At some point, elected positions need to be done for some people. It’s time to go do something else.

Billy isn't interested in DC, he wants the Governor's office.

He likely made deal with Landry like he did with Edwards, he won't say nor do anything negative against him in the election in exchange for a big role at the Governor's table.

Billy will run again for Lt Gov not just in the next election, but very likely in the one after that (assuming the winner of the next election is GOP and does a good enough job to likely win re-election in 2028).
