Needs to stay in this race, even though I think that much of his support would go to Bernie if he dropped out.

The more populist voices we hear on stage, the more Hillary sounds like the voice of Wall Street. Also, he may not win this year, but he is establishing himself as a party leader for the future. Don't stop!

BTW - yeah, "Marty"! We have Bernie, Hillary, and...Martin?

On the one hand, we could say that Martin is too much like Bernie, and maybe that's why his poll numbers are lagging. But on the other hand, it does flesh out the populist field in this presidential race, and drives home the point that this populist phenomenon isn't just some fly by night or fringe thing. Perhaps Martin and Bernie together have more power to isolate and marginalize Hillary Clinton as being too establishment and corporatist in her views and positions. Maybe Martin does need to stay in this race. He is still young and up and coming, unlike Bernie, and is also securing a position for himself as a leader in the party - and if he wimps out now, he won't earn those credentials. Boy, is the road to the White House ever long, arduous and expensive!
