Pelosi's is the supposedly "safe" route. However, I'd argue that it is a politically winning and legally/morally/ethically totally justified to pursue impeachment.
The POTUS is compromised. If he were any regular Joe Citizen he would be indicted. Given everything we knew before, what we know today and what is coming via the 20+ additional investigations currently underway there's no question your father, your husband, your son or your neighbor would be frog-marched off to the penitentiary.
No man is truly free if some men are above the law and it is people like Donald Trump who rob you of your freedom, your liberty, your dignity. When does it stop? Only when men of good character say "enough".
