And if he loses, as every reality-based analysis points to, what will he do? I'm not expecting a suddenly humble Donald Trump to make a cordial concession speech. I'll be surprised if he concedes at all. But what I fear most is Trump calling for his followers to resist the results.
I think state and federal emergency planners should be preparing for what might happen. But how do you prepare?
First, emergency planners should consider likely scenarios in their particular regions. Here in Massachusetts, the election results are unlikely to be close, so I doubt people will be storming the town halls to 'guard' the ballots. I don't know what is likely to happen elsewhere--that's the kind of local knowledge I don't have but emergency personnel in each area hopefully will have.
The planning for election day and the days around it should be the sort of thing that is familiar to any police department that's had to deal with a controversial trial. Having plenty of personnel on schedule or on call is a good start. Identifying flashpoints is also important. I can't guess much beyond that because that's never been part of my job. It is part for their job, and it's definitely something police chiefs should have underway. I wouldn't be surprised to hear from some national groups making public service announcements about 'American tradition' and 'safe and respectful voting' and 'listening to the voice and votes of the people.'
I'm glad I don't live in a state where open-carry enthusiasts might converge. Hopefully, planning in Texas is well under way. Philadelphia has already been targeted, so they had better be planning too. Other areas where the danger is higher: Georgia, Arizona, Florida, Ohio, Nevada, and maybe others.
Despite my concerns, I expect a strong and well-planned response by police and government, and minimal trouble with minimal injuries and damage. Not none, but minimal.
Maybe a few days after Election Day, Trump will realize that he can't provoke much reaction anymore, he will good and defeated, and a major threat averted. We shall see, but planning now is important and shouldn't be overlooked.
