For one day this week, the 2020 Democratic primary included “Gory BOOker,” “Steve BOO-lock” and “BoOOLián Castro.” How’s that for Halloween spirit?

We’ll return to the holiday later. For now, here’s a look at the more substantive things that happened in the race this week.

Beto O’Rourke is out

Former Representative Beto O’Rourke of Texas ended his presidential campaign on Friday, saying he had concluded that “this campaign does not have the means to move forward successfully.”

“My service to the country will not be as a candidate or as the nominee,” he said in a message to supporters. “Acknowledging this now is in the best interests of those in the campaign; it is in the best interests of this party as we seek to unify around a nominee; and it is in the best interests of the country.”
