"It is essential to note that an electoral mandate does not give a president of a democratic state a blank check to do whatever he and his party desire but merely authorizes them to implement their campaign commitments within the bounds of the government's powers in the Constitution and its explicit and implicit principles."
Unfortunately, that quotation did not come from an American newspaper. It came from the Taiwan Times*, which then quotes their Constitution as holding that "the sovereignty of the ROC [Republic of China, formal name for Taiwan] shall reside in the whole body of citizens."
When we put too much hope or trust in a Presidential candidate, we risk giving up part of the sovereignty that rests in America, as in Taiwan, with the States and with the people.
* This is in the context of allegations that the president is attempting to negotiate away Taiwan's sovereignty in secret negotiations with the People's Republic of China -- something we will probably need to think about in the context of the "North American Union".
