I doubt it will be a landslide, although a 2008 Obama-style comfortable win is now certainly on the table (as is still losing the election). The one thing that has surprised me about all this is how unprepared Trump's campaign obviously was for Biden stepping aside and Kamala getting the nod, and now for Walz being chosen. If there's anything the GOP has usually done very well over the past couple of decades it's in the fields of grassroots campaign organization, opposition research, PR efforts to frame Democratic opponents based on their weaknesses, and campaign strategy. But so far this year Trump's campaign and even the usually reliable RNC have just bumbled and stumbled and proven to be strikingly inept at almost every turn. Biden's debate disaster just fell into their laps, they didn't cause it. Whatever has caused the decline of the GOP as an effective campaign organization, I certainly hope it continues right through the election in November and (hopefully) well into next year.
