"Far left fact checking site"? Where's your independent source to verify that? Have you seen what they say about left-leaning news sources? I think they call it pretty fair.
I think Trump is very effective in his craft of manipulation. You and several others think any criticism or reporting that is perceived to be negative in any way is automatically a lie by default. He has exploited his followers' fears and paranoia by continuous and relentless attacks on the mainstream media to discredit it. In doing so, he has created a world where he can do no wrong. So now anytime he f**ks up and there's a story about it, all he has to do is call it fake news and his followers believe him. Actual success doesn't matter to him, it's the appearance or illusion of success; that is what he's so good and effective at.
Getting back to the meme, the focus isn't whether or not Trump's crowd size was smaller or whether the photo is fake or not (In reality, it's a real photo, though it may have been taken sometime prior the start of the ceremony). It's the fact that he spends so much brainpower fixated on such a MEANINGLESS topic because he's THAT thin-skinned. If he never gets up there and boasts and exaggerates about the size of his crowds (calling it the largest audience to ever witness an inauguration, which was demonstratively false), this photo doesn't circulate and it never becomes a story we're still talking about four years later or a meme.
The fact that this struck such a sensitive nerve in him demonstrates his unhealthy obsession with Obama and his insecurities when measured up against him. It's another reason he has indiscriminately removed any and all things with Obama's footprints, including eliminating the WH pandemic response team, the Global Health Security and Biodefense unit, established in 2015.
Democrats will vote for Biden and Trump will lose this election in large part to his pathetic and disastrous handling of the pandemic. And when Biden's inauguration crowd is smaller than Trump's, due to his voters' understanding of the severity of Covid19 and the importance of social distancing, he won't cry and poop his pants.
