For "any reasonably liberal president" read Democrat.You express yourself just fine in English, mate. I really do believe that Clinton didn't see the anger across those who perceive themselves to be disenfranchised, and Sanders' potent campaign against all odds should have been a warning sign to her and others that many Americans were angry with "business as usual" in DC. Obama was more a convenient target I think. I am betting any reasonably liberal president would have suffered the same fate unless he/she had the charisma of Kennedy.
The Republican party has become the Obstructive party. Thankfully they still are under this reasonably insane president.
