Transportation Secretary Pete Buttigieg has emerged as the Democratic Party’s debating guru, a position crowned by his coaching of Gov. Tim Walz (D-MN).

In preparation for Walz’s debate with Sen. J.D. Vance (R-OH), Buttigieg has taken on the role of former President Donald Trump’s running mate to prepare best. The coveted position reflects the Democratic perception that Buttigieg is a king of debating among Democrats.
