以往的美国总统,说话还是很注意的,因为他们觉得他们的话将会改变世界或改变历史:

Like Roosevelt, every American president before Trump has operated with the sense – if not always the practice – that every word they said in public had vital and profound significance and by the conviction that their words had the potential to shape world events and alter history. When running for president in 2008, Barack Obama reflected on that power. “Don’t tell me words don’t matter,” Obama said to an audience of Wisconsin Democrats. “‘I have a dream’ – just words? ‘We have nothing to fear but fear itself’ – just words?”

但老特则不然，望之不像人君，说话偏激、善变、口不择言，全无古代帝王“金口玉言”的意思。反正话说得不合适了，白宫发言人就说总统只是“说笑“而已。

A lot of ink has been spilled over President Donald Trump’s continuous stream of outrageous words, with the commentary tending to take one of two tracks. The first concerns the offensiveness of Trump’s coarse and crude language, the atrocity of having a president who routinely spews hateful and divisive rhetoric. The second focuses on Trump’s penchant for lies, his constant habit of changing his story from one day to the next – and sometimes even within a single sentence.

Trump has brought a much different sensibility to the presidency, one warped by his self-assessment that he has the “best words.” It is also influenced by Trump’s belief that speaking his mind is what got him elected in the first place; by his sense of himself – shared by his unflagging supporters – as a tell it like it is straight shooter who was slicing through a culture of political correctness with common sense and hard truths the American people craved to hear.
