Alito and Thomas had multiple chances during the Obama years. Every single NBC case that found its way to the SCOTUS docket was dismissed without comment.
With Obama, he was born in the US, of a US citizen. With Kamala, she was born in the US, of two foreign citizens. The two are entirely different.
I remember every argument against Obama was just that, and the argument was, if he was born of two foreigners, he wouldn’t be eligible. That is called moving the goal posts writ large.
