'Just, how? '
I don't know how, I am not a politician. Trump says he will put New York's and America's best brains in chgarge of trade deals. His mate Carl Icahn will be sorting out trade with China. Trump says there will be no more "political hacks" ad friends of the Establishment who are unqualified in business but are just there because of favours and who they know.
Trump will change laws in America. The finest legal minds will be on the case. He will get it done. How, I don't know, but he is not running to mess around or get backhanders for his foundation or charidee. He is running to fix America and help the American people.
'The president has very little impact in the economy unless it's backed by Congress and Senate. '
Yes and at the moment the Republicans have the majority. The Republican elite will have to fall in line with Trump and work with him.
'Which he may not be if he goes so much against the establishment as he is supposed to. '
I think he will end up being so popular and we already know how unpopular they are with the Republican base, that they will have to go along with Trump.
'He'd have to play the game just like any other politician who reaches power and doesn't have absolute power.'
I agree. But that is his great skill, he is a dealmaker, he gets on with people (unlike Cruz) and he will get the job done by compromise. But as we have seen throughout this campaign, Trump is tough as nails and no one will get the better of him. He is ruthless in his aim to serve the American people and no puppet politician will be able to stop him.
