Should Beto's exit be a signal to other struggling candidates to call it a day?

Let me be clear firstly, I have no issue with anyone running but now less than a hundred days to Iowa and just two more debates in 2019 to go, the field should be clearing up IMO.

In someone like Michael Bennet's case I feel sad because he is a fine man and a principled Democrat. But he hasn't made the last few debates and his polls have never grown. He has never had any traction. Then you have Cory Booker and Julian Castro who tackle issues of social justice as well if not better than anyone else but whose campaigns were on life support as they needed to raise a certain amount by a certain date just to keep going. And still have issues with qualifying for the next debate.

Beto didn't resort to that - his campaign didn't have the means or path ahead so that was that. It didn't work out for him now but he has a bright future whichever path he takes. I actually respect him more now because it takes humility to drop out. Especially when everyone had high hopes.

Therefore perhaps it is time for others to admit that if he dropped out despite having the energy and excitement among his base, despite qualifying for all the debates up to now, despite being a target of the Republicans, despite having the strongest financial numbers initially, despite having an element of name recognition...then the ones who don't have any of that need to follow his lead.
