“He knows IF he drops out, he becomes eligible for indictment.”
Ha!
The fact that he was running for President never made him immune from indictment. That was always just a red herring - a fake news narrative suggesting that it would be a conflict of interest for Trump’s DOJ to investigate or indict a political rival, because it would benefit his re-election.
Legally speaking, that is baloney.
The DOJ was free to indict the Bidens at any time, regardless of Joe Biden’s status as a Presidential candidate. Biden’s defense could TRY to argue that there was a conflict of interest, but to beat that, all the DOJ would need to show is probable cause.
Trump ought to hit Biden with a subpoena right now, and revive Biden’s campaign and throw the whole damn Democrat thing into complete chaos.
