I share same politic views than my T and I absolutely like the fact. I think I would have hard hard times if she represented total opposite views. I am slightly into politics myself and the way I know about my T's views is because I have told her mine and about my activities and then she has disclosed that she agrees with me there and we have talked about potitics. I was very natural situation and my T is not secretative anyway. I guess if I had told her I am for something else, she wouldn't have shared her views as I think it could be damaging to the relationship to know your T shares a complete different set of values.

And I guess if one can continue with a T thinking very differently depends on how big of a role these things disagreed with plays in life. If they can be put aside and the T is helpful, then the political views maybe can be put aside and keep working together. But if there is a "dealbreaker" among the things disagreed, it might be be a bad combo.
