Phillips
At least De Blasio made a debate
DeBlasio had nothing to gain but nothing to lose whereas Phillips had nothing to gain and everything to lose.
In regards to DeBlasio I was also thinking of this:
Still DeBlasio.
Phillips was running against an incumbent president who governed well, which wasn't even disputed by himself. DeBlasio though was the mayor of America's largest city and got utterly destroyed in a House primary.
Although to be fair DeBlasio didn't lose because he dropped out before the primary...but the fact that he even ran in the first place is what's perplexing because he obviously had no chance. And yes he's very very very far from the only person to launch a hapless campaign he had no chance in, but of those people should be pretty high in the list of people who were aware of how doomed it was.
