Why is getting elected proof of intelligence? We literally elected the guy that convinced an overwhelming number of uneducated people that he was going to build a wall to keep the illegals from stealing their jobs.

Illegal Immigration does have an affect on blue collar jobs. You can research this yourself, btw. There is a truckload of studies.

I actually can't tell if you're being sarcastic.

Intelligence is not a prerequisite for being elected, and in many cases intelligence is a disadvantage. Most people are stupid, and they would rather see one of their own in positions of power. Dumb people can more easily connect with certain areas of the electorate.

Examples of this phenomenon are so copious and obvious that I shan't point them out.
