SO, the orignial baiting question was what does "Make America Great Again."

Even though meant to bait an argument, it is a good question. Having a good economy would be a good start. WE have a terrible economy right now, never achieving a 3% GDP in one year in the last 8 years. A record of poor GDP growth.
Getting people off of food stamps would be a pretty good step. We have 45 million on food stamps. Another poor record
Home ownership is supposed to be lowest is has been since WWII
We have almost 95 million people out of the work force according to the Bureau of Labor Statistics
I could go on, without blaming anyone, but just giving statistics, you should be able to get the idea. A better military presence, etc.

But, anther good question, I believe is:
What does it mean to stand in front of the slogan: Stronger Together and tell millions of people that they are deplorable and irredeemable?
