I can imagine a scenario where he goes on tv and publicly resigns, blaming Republican intransigence and white guys, before any movement to impeach him goes full steam.
Besides, impeaching means nothing unless he is also voted to being removed from office. All it means is that he can’t run ever again.
Bill Clinton seems to be doing well, despite having been impeached.
Obama will not resign. And he will only be impeached if the democrats realize he’s destroying their party. Period.
If the dems decide he’s toxic then and only then will he be impeached and convicted until then he knows he cAn violate the law with abandon
