No one can predict how much success any president will have with Congress. The most respected man in the world in 1918 was Woodrow Wilson. He was regarded as a near God in Europe and when he returned to America with his fourteen points and his League of Nations he was eviscerated in the Senate. He went to the people but had no success even before he was brought down by a stroke. Richard Nixon was elected with huge majorities and was one of America's smartest politicians yet the Democrats succeeded even in driving him from office in disgrace.
Trump will have neither the Republican establishment nor the Democrats in his camp and he will not have the whole of America as you suggest with which to intimidate Congress. Trump's bombast is appealing to you and me as hardheaded conservatives but it does not play well with soccer moms and the great bulk of the American people who do not live politics 24 /7. Barack Obama has been able to rule free of constraints from Congress for three reasons: 1) he is African-American and therefore it is illegitimate to criticize him-or has been for many years until recently; 2) he is a Democrat, note that Roosevelt, Kennedy and Johnson and now Obama have committed the same or worse crimes than Richard Nixon but they were never near impeachment; 3) Obama conceives of his legacy not in conventional terms but in the degree to which he transforms America.
Trump will not necessarily fare well in office with his outlandish bombast, the Art of the Deal to the contrary notwithstanding.
