I say "You can come, but it could be a natural death sentence; Temperatures in cities west east of the rockies get very, VERY cold and you will need to survive by living in a tent because we are out of residences."

Unless you can build a house in the next 6 months, own a motorhome, or are on the west coast, you're better off seeking asylum anywhere else that will take you first. I hear Japan or - if you have to - China have a few unoccupied buildings whose property values are affected by their plummeting birth rates. Look into those first, then any nations you have second citizenship in, then take your chances surviving our brutal winters (if you live in Michigan or North Dakota, you already know what kind of temperatures I'm talking about), and good luck.

And that concerns me for Canadians. If things continue on a downward trend, Americans with serious money (note: I do not have "serious" money) will head to Canada, further exacerbating the housing shortage.

Hang in there and keep an eye on the west coast. If California votes in favor of secession, sell your house or get a loan for it as collateral, buy a motorhome with the money and go to northern California (preferrably somewhere near San Francisco). It's super expensive (or at least it is at the time of writing, this being the place Silicon Valley is located) but, provided that California has already confirmed secession, you'll be as far as you can get from "his" influence without leaving the Continental US.

Other options if you have no other citizenship are Hawaii, Puerto Rico, American Samoa, Alaska and the Seattle area. If you can cross a border, head for Kelowna in British Columbia. I do not recommend trying to get through Texas to Mexico, there are a lot of culturally-engrained prejudices that you're certainly familiar with that will have them questioning why a family would flee Florida "unless they're trying to escape" and pre-emptively detain anyone traveling in a motorhome with their entire family. If possible, drive as far north as you can before turning west.

Use OsmAnd (an android GPS app that uses OpenStreetMap instead of Google Maps) on a cheap phone for your navigation, toss it and your normal phone if you have a close call. If you have ANY access to leave the country for one of similar safety for ANY reason, research their current state using wikipedia. Buy your tickets for an airline now and then prepare legal resources to apply for refugee status in the country you end up in (might take several long-distance calls). Worst-case scenario, you take your chances of being deported by creating a change.org petition and hope that the recipient country understands you're not leaving the wealthiest country on earth if shit hasn't hit the fan (they probably will be willing to listen). All of this is legal but will also keep you out of trouble if legality is not a barrier to those currently trying to take complete power in the US. Please note, I'm not an American or a lawyer, I just have a surprising amount of life experience. Good luck.
