Four years ago, out Transportation Secretary Pete Buttigieg was enlisted by the Biden-Harris campaign to play the role of former Indiana Gov. Mike Pence (R) in mock debates with then-VP candidate Kamala Harris. Buttigieg, one of Indianas most prominent Democrats, perhaps had insight into Pence that other people associated with the campaign did not.Apparently, he really helped Harris prepare for her debate, and now hes taking on a new role, that of Sen. J.D. Vance (R-OH), helping Minnesota Gov. Tim Walz (D) get ready for his vice presidential debate, scheduled for October 1.

Kaine was the Democratic vice presidential nominee in 2016. While vice presidential debates generally arent thought to swing election results, Paul said that this years might be different since Harris and Donald Trump may only have one debate themselves. It seems this year, without a full presidential debate schedule and where this is falling in the race, it has somewhat raised the stakes of this debate, he said. Four years ago, Harris tried to dampen expectations ahead of her debate with Pence, and Walz is doing the same this week. Look, hes Yale Law guy, Walz said, referring to Vance. Im a public school teacher. So we know where hes at on that.You will hear me talk, like I have, about things that impact Americans making sure they have the opportunity to thrive, making sure that were being factual in how we talk about that. And so Im looking forward to it. I will work hard. Thats what I do. I fully expect that Senator Vance, as a United States senator, a Yale Law guy, he will come well-prepared.This debate will serve as another clear opportunity for Governor Walz to present Vice President Harris winning vision of a New Way Forward to the American people who are ready to turn the page on Donald Trump, said a Harris-Walz campaign spokesperson.
