Could be worse, imagine if he delayed it because of Ramadan so his Muslim supporters could attend.
It’s hypothetical, of course. Ramadan doesn’t fall out in December or January this year. Besides, the supporters could attend even during Ramadan. They’d just be in a crappy mood for fasting. For that matter, Shabbat observers could attend just by walking to City Hall. If they live in Brooklyn, they could walk the Brooklyn Bridge. That’s always a thrill. If they live in Queens, I’m not sure there’s a pedestrian walkway across the 59th Street, and that’s a pretty formidable schlep besides. If they live in Staten Island or the Bronx, they’re out of luck.
Ramadan won’t occur in early January for at least ten years.
