Getting back to the title of the thread... I'm not an expert on US politics but from what I understand Trump is disliked as much by by the conservative establishment as he is by the liberal one. So, looking from a far he's either going to have to compromise with his republican party's backbone or he'll never get anything through the congress & senat. In other words, toe the line or be lamer than a duck with stage fright who can't swim or fly.
Another point, Trump lacks any kind of political experience which gives me the impression he won't have a clue what he's doing in office. I guess he'll need the support of experienced politicians in order to be effective.
