Chris Wallace on impeachment, Buttigieg and smart reporting

• And I asked Wallace how impeachment is playing in the Hawkeye State: "Voters are asking what the mayor thinks about impeachment. So we will reflect that in the town hall. But I don’t get the sense anyone thinks the president is actually going to be removed. So it just factors into how folks think about Trump."

Buttigieg senior adviser Lis Smith told me why the mayor is going on Fox News: "We know we can't win the primary or general by just talking to the same people over and over again."

• "Our campaign is also about elevating qualities like respect, decency and thoughtfulness in the political discourse," Smith continued. "Those are definitely qualities that Chris embodies. ... He's a tough questioner, but he's fair and has established a massive platform for himself."

A reporting tip from Chris Wallace: Instead of just interviewing aides when he's doing background reporting, he tries to talk to the Cabinet members and lawmakers themselves: "Often they don't know what's out there or don't know the talking points, and they tell you more!"
