There are quite a few performers who try to keep politics out of their sets, even if they are on the liberal side. Dave Van Ronk is one example. Ronny Cox has said on Facebook that he doesn't expound on politics in his shows. I like songs with teeth in them, so they tend to make a point, but I don't believe we make overt statements between songs. I have sometimes said any conclusions drawn from the song are purely the listener's.
