Not going to say this is accurate but David Plouffe knows a thing or two about running a campaign and winning elections. Jen O'Malley Dillon is extremely sharp as well. The ground game in Wisconsin, Michigan, and Pennsylvania for Harris is quite impressive. DT Barnum has little to no ground game. If Harris/Walz win the election, the GOP will almost certainly rue the day they decided to hand the reins of that party to Lara Freaking Trump.
If you follow things closely, Plouffe's tone has changed a bit. He sounds optimistic, hopeful, and . . . dare I write it . . . confident that things are breaking in Harris/Walz' favor. There is very little denying the stark contrast between the tone/mood of the two campaigns right now. This may not translate into a Harris/Walz win but I've become more optimistic in the last 72 hours that DT Barnum will be saddled with his second loss as a presidential candidate.
