I think treason would be hard to prove, but this case appears more solid that the case Jack Smith had against Donald Trump over that insurrection nonsense. What these people did was attempt to prevent a duly elected president take office and carry out his duties. Compared to the J6 charges of obstructing an official proceeding, what the Obama team did was far worse, and closer to insurrection and conspiracy to commit insurrection that anything anyone did on Jan 6.
And by the way, do not forget the names of Sally Yates when talking about his crime. She was in the room and orchestrated the takedown of Michael Flynn.
Do not omit Samantha Power either. She requested the unmasking of over 260 Americans names from raw intelligence report. Then denied it but has never explained what she actually did do.
And lastly, remember the name Evelyn Farkas. She's the one who went on TV and bragged about the info gathering network inside the government that was in place to collect dirt on Trump and prepare it for the eventual impeachment cases that would follow. Then she recanted. but that was after she realized what she had done.
