ELI5: How can congress stay in office for so long and be reelected regularly when approval ratings is so low.

Because everyone has the tendency to say that it's everyone ELSE'S representative who sucks, but tend to believe that theirs is okay.  

Also, because when the election comes up, it turns out people's party allegiance is way stronger than their hatred for Congress.  So even if they despise their representative, they'll still vote them in before "the other guy."
