My man, I hope you're not American because the world has a laundry list of complaints against America. People care about different things to different degrees. You compromise on who you think is the closest to your positions. In a country of 1.3B people, there is always divergence of opinion and in fact nearly no-one would have even thought about immigration as a concern when voting.
There is a difference between the personal things you can influence and being the 1/13000000th voice of the people.
