BUT OF COURSE IT'S NOT A SUPERSPREADER EVENT: At least 63 people on Martha’s Vineyard have tested positive for Covid-19 since Barack Obama’s maskless 60th birthday bash.

Looking online there appear to have been 300-500 guests at his soiree so, assuming all the cases resulted from the party the infection rate was about 18.0%.

Compare that with 2020's Sturgis motorcycle rally: the data I've seen indicates that there were about 414 infections (nationwide) that could be associated with the rally. The estimate of attendance over the multi-day rally was about 462,000. That's an infection rate of 0.09%.

Again, which one was the 'superspreader'?
