Clip from a PBS Newshour broadcast of Obama, via YouTube.

It has been a long six years. At this point six years ago, President Obama was Candidate Obama -- energized, engaging with voters, bounding along the campaign trail. At his news conference Friday, he looked different, leaning on the lectern, wearily answering questions from the media.

So here is our challenge to you. Presented with a series of GIFs depicting Obama news conferences, can you identify which Obama it depicts? Is it 2009 Obama, fresh on the job? 2012 Obama, balancing running the country with running for reelection.

Go find out. It is harder than it looks.
