Would she be able to automatically take up the POTUS position and get things rolling from day one? Absolutely. She's a career politician, she knows everyone in the system, she knows how to play the system, and she knows how to work the system to her advantage. She can even ask Bill if she has questions. Ha! (Can she just divorce him now?) But she has sold political influence to make herself wealthy and let ISIS take hold of the Middle East on her tenure as secretary of state. What ISIS has done is destabilizing not only the middle east but all the European countries the refugees are fleeing to.
Trump has no political experience aside from golf with the Clintons. He will have to surround himself with people who have that experience and expertise, but at least he's been a CEO, so he does have leadership experience, just not in politics. He's going to have to be a top notch CEO of the US who seeks out absolutely the best people to fill the jobs and then lets them do their jobs without micromanaging. His advantage is that he is not "Bought"--he doesn't owe favors to Monsanto, Dow, Merck, the King of Qatar, or anyone else. He was abandoned by the Republican party and vilified by the Democratic party. He doesn't owe either party anything, and that sets him free to actually reach across both aisles and not pay lip service to it. He's going to have to make amends for what he said during the campaign and to try to unify where he created division. Yet, he doesn't feel the need to be politically correct, so the variety of issues that are plaguing our country-- the issues that everyone tries to pretend don't exist during the election campaign, he has the guts to say it like it is. And things are bad--social security is going broke, we have Islamic terrorists setting up cells in our country, we have a $20T debt, and our politicians are beholden to companies, not constituents. It's not going to be fun or pleasant for us to face these issues as a country, so having someone who is willing to say it like it is and doesn't need to kick the can down the road to appease a political party is an advantage.
