Meh, it's just a continuation of an ongoing trend. It would doubtless be the same no matter who is president.Your chart demonstrates that Obama took a bad thing and made it worse. Things got better after fracking, which Obama opposed.
Trump has continued the trend of improvement.
The top poster doesn't know much about charts apparently. If you look closely you'll see that the 2008 crash caused the spike in unemployment. So by the time Obama was done with his term the only thing he did was preside over the recovery back to original employment levels which werent all that good prior to the crash. In other words the bounce-back was going to happen reflexively with or without Obama's presence. The progress made in decreasing unemployment under Trump is above and beyond what the 2008 levels were.
It's now time for the top poster to Homer-slap himself in the head and say D'oh!
