Bill de Blasio -- who is somehow still mayor of NYC until 2021 (there's a good race to jump into Cynthia Nixon) -- has dropped his bid to be the Democratic nominee for the 2020 Presidential election, gaining more press in his withdrawal than basically his entire campaign. Wait, correction: He actually gained quite a bit of press when only 15 people attended a rally of his last month in Iowa.

I'm not sure exactly what de Blasio was running on -- some generic form of progressivism -- but based on his performance in the debates, I'm pretty sure his entire campaign was predicated upon mansplaining other people's ideas to the American public. "Oh, sure! Elizabeth Warren's got a plan, but let me tell you about it, only louder and manlier!" I'm not sure how de Blasio actually won re-election in 2017, but a quick look at Wikipedia suggested it was because no one formidable bothered to run against him.

"I feel like I have contributed all I can to this primary election," de Blasio said on Morning Joe today. He's right. He contributed nothing, which is all he could spare.

And with that, there are only ... 16 or 17 candidates left? Either way, it's quickly shaping up to be a two-person race, between Joe Biden and Elizabeth Warren, who lead in both national polls and in Iowa. Note, too, that in 2007, October - December were critical months for future President Barack Obama in his race against Hillary Clinton. That's when he wrestled the Black vote away from Hillary. The ultimate success of Warren -- who has locked down the college-educated white people vote -- may rely on her ability to do the same thing.
