@Lash,
My answer to your question is:
1. I think Bernie Sanders sees a big difference between the democrats and the republicans?
2. I believe Bernie Sanders caucuses with the democrats because he agrees with the democrats more than he disagrees with democrats.
3. I believe Bernie Sanders chooses
not to caucus with the republicans because he strongly opposes the republican party and the views of the republican party.
Now that you got my answer, Lash.
Now it's your turn to answer.
Unless you don't want to answer, Lash.
