Do you think he is doing a good job so far?
You mean Donald John Trump ?  the 45th and current President of the United States, in office since January 20, 2017
yes i do how do you think he is doing?
With his vast business experience, he should be able to manage America well.So far ,he's doing well
How does running a business equate to running a country? Are you worried about his multiple Failed businesses and multiple ongoing lawsuits?
Business and leadership are interwoven my friend.Lawsuit is a requisite .With all the negative media hype ,he still won the election
but the mindset of running a company and running a country have to be vastly different. You're held to a different regard as the leader of the free world.
Trump earned an economics degree from the Wharton School of the University of Pennsylvania.It's all about management of man,machine and money.That's leadership in business and governance
So on his Business acumen what about all of the failed companies hes had and the lawsuits surrounding them? examples being some of his hotels as well as Trump college? 
Are you a business person? If you're not,you won't understand ! Lawsuits are normal in every aspects .Its a normal business expectations
