America, the USA rather, is not for people who like sanity in their political representatives. Sure, we might have a handful of sane politicians, but when they come together in a mass, all semblance of sanity is out the window.
The US is not for people who like where they are and where they are is not the US. A lot of people would much rather stay where they are than move to the US. Many of them would like the economic opportunities of the US, but not enough to make leaving their homes worthwhile.
