He is actually not the only to keep his campaign promise. One other president promised not to run again if he won. He won and did not run again. So Trump's not the first.
Beat me to it. I was thinking of posting a similar meme. The Left supports all of those liars that make promises they never keep. That was OK by them as long as they were left. The Right supported all of the lies by the Republicans they were Conservative...at least in the campaigns they were. Then we get a guy who says he's going to do this and that and gets elected and actually does it? BOTH sides are going crazy.
