For someone who prides himself on optics, Barack Obama just gave us quite an ugly spectacle. As the rest of America struggles with uncertain employment status and school reopenings, shifting mask mandates, anxiety over vaccinations and variants, the health of the economy and the citizenry at large, Obama had to go and throw himself a huge, epic, three-day birthday bash on Martha’s Vineyard. You would think a former president — one who clearly considers himself more intelligent and sensitive than most — would exercise some restraint. Or at least understand that this was a supremely bad look. Here was our climate czar, John Kerry, flying in private. His mode of travel was preferred by a host of left-leaning eco-warrior celebs, all Obama’s “close friends,” of course, descending on an already understaffed and emotionally depleted Vineyard. “His birthday party is insane,” one of Obama’s caterers told The Post last week. “What is he thinking?” Clearly, Obama thought to do whatever he damn well pleased — even after such backlash caused him to effectively cancel his party. Is there a more disgusting display of elitist “Rules for thee, not for me” than this?
