I have a better idea. Lets sell Washington DC and surrounding area. Lots of educated people.
You are on the right track, but the problem isn’t just there. Let’s sell:
1) CA
2) NY
3) Chicago
4) WA State
Without these areas voting (in many cases multiple times) we will be able to get much better government. In addition, what of any value has any of these areas given us in the last 50 yrs?
Don’t forget New England...six liberal states conveniently packaged together! You could offer a ‘group rate’...
