One of the most important insights I heard from the commentary last night came from Chris Hayes on MSNBC. He pointed out that while the campaign is leaning heavily on Walz’s biography as a small town teacher, coach, soldier and family amn, all of which is true, it’s important to remember that Walz also spent 12 years in DC as a congressman and has been a very successful Governor of a big state. Walz is a great politician — an astute, experienced public official who knows how to communicate effectively and enact an agenda. If something should happen he would make a great president. This choice speaks very well of Harris’s political judgement but it’s also speaks well of her seriousness of purpose.
