I can believe there are fewer people in the 2017 photo, but I’m wary of internet memes. Is the comparison a true depiction of the audience? Or are the times inaccurate, or otherwise ‘cherry picked’?
I would not be surprised if Obama’s 2009 inauguration numbers were higher than even Bush II or Clinton’s, never mind Trumps.
Obama was a charismatic candidate who had a large devoted following, especially amongst minority and younger voters, both of whom came out in unprecedented numbers to support him.
I was in London at the time and the day of the inauguration was a party atmosphere in Central London with people watching the proceedings on giants screens, in pubs etc. I can only think the enthusisam was much greater in the US.
I can confirm the international aspect of the enthusiasm. A friend was in South America at the time and said the crowds were ecstatic. Remember, of course, that not only was Obama a charismatic candidate and one whose platform was exciting and enticing to many people, he was following an immensely unpopular presidency at a very precarious moment. Say what you will about his shortcomings and failures, (thanks, Mr. McConnell et al) his crowds reflected what many in the U.S. needed at that time - real hope and change. While many Americans may be disillusioned about the functioning of their governments, Obama was far from the disaster that Bush was and the crowds today probably reflect some of that.
I wouldn’t be surprised if it was accurate, if you’re talking about Obama’s first inauguration; there would have been a considerable number of people who wanted to witness the first African-American being sworn in as President firsthand.
It also wouldn’t be that surprising if Obama’s second inauguration had more people there than Trump, given that it was held not only on a holiday, but the Martin Luther King Jr. holiday at that.
