Nah, as much as I can’t stand Glenn Greenwald. He called this ages ago, he will be an absolute martyr if the impeachment is successful. If it isn’t it will make his already rabid supports force a landslide.
But either way, him and his family are already under multiple investigations which they are being shielded from as he's the president. Once he's out, whether its next month, next year or next term they will all be waiting.
The only way he will not end up in jail is if he cuts a deal.
