The saw about politics applies to all of it: the process of making a bill, like that of a sausage, ain't pretty. 
Politics is a blood-sport. Everyone gets splashed, mangled, transformed.
But a democratic republic is the best system ever devised. Imagine if liberals/progressives had refused to vote until the perfect (whatever that could mean) candidate came along. We'd be a country to the right of Putin's Russia by now.
Any observer of American history must see that progress always has come slowly---------- but it HAS come.
I align myself with those who feel that a society should be judged by how it treats its least powerful citizens. African-Americans, during my lifetime, have vastly improved their lives, overall, but a long struggle remains.
I cannot imagine a Latina or a Muslim smiling at Ms. Porter right now. Her lackadaisical approach to their real issues must be frightening. A Trump presidency greatly would disturb or ruin their lives.
