Trump is fixing problems long before he becomes president.
Imagine what he can get done when he has authority and power.
You are right, of course, but if you think about it, he DOES have the authority and power of all of us - millions of people - having stated in a clear voice that HE’S OUR GUY!! He may not have the official mantle yet, but IMHO, he DOES have the power! That power is US! And he’s using it on our behalf!
