Crowd estimate was 20k people - the line to get in snaked for over 10 blocks, zigzagging through downtown Milwaukee - it's the longest line I have ever seen. The crowd was rowdy, and larger than they expected - I was too far away and near the door to see Katy Perry, but I did see O when I stood on my tippy toes. His voice was hoarse, but his message was clear, and Wisconsin went crazy for him.
Tammy Baldwin also spoke, along with Herb Kohl, Gwen Moore, and Tom Barrett.
An observation - a lot of young people and a very diverse crowd.
I was very encouraged by what I saw, and super excited to see O for the first time.
