They also don't realize there could be some cultural differences and push for changes that the original people don't want.
On a side note, I have a neighbor that decided to run for local office the first year he moved to our town. I found it interesting that someone would want to run for office before getting to know the people, not to mention that's a pretty quick time to form opinions about the town's politicians to the point of wanting to take their office. I guess it doesn't matter since he wasn't elected.
