of which I was able to see, either in real time or on video, just about all of the events.
The most obvious thing to note is how comfortable Clinton & Kaine are together. That comes across, and helps to connect with the various audiences.
It is obvious both parties recognize the importance of the two states toured, because the two conventions were held therein. For the Republicans, none of their candidates has ever been elected without Ohio, and Pennsylvania has remained elusive for the last 6 elections. From the standpoint of the Democrats, hold both of those states and it becomes very difficult to imagine a path to 270 electoral votes for Trump. In fact, if Clinton were to win those states, lose FL, GA, NC, IA, VA, NH, NV & NM and all other states perform as they did in 2012, you would have a tie.
Let me note several things I observed reasonably consistently at the various events, and offer some thoughts about them.
