Oprah probably wouldn't be a very good president. She'd be too focused on the problems going with other countries than ours. She wouldn't be very good with making political decisions. Sure, she'd be able to get rid of some of the problems going on in the world, but she wouldn't be able to handle the U.S.'s problems with going to war.
Basically the only major things she can accomplish would be stopping problems that do not really cause a lot of harm to the rest of the world. Yeah, all of that stuff is important you know yeah there are people starving and we aren't really doing anything about it. But like she would not be able to handle taking care of all of the rest of the events that are going on in the world. No matter what, she'd be overwhelmed with all that is going on in the world today and would just end up resigning.
Oprah could probably open so much more schools if she had that kind of power. But she would not be able to be there to attend the grand opening to all of them, she would be too busy with other important things. Being president is already a lot of work, she has a lot of work already, do you think she could even accommodate all of the hard work and effort? Opening schools would be great, but she probably wouldn't be able to open as many schools as she does now if she becomes president. There is no way she'd have enough time to do that.
