Former Governor and Senator Lincoln Chafee of Rhode Island ended his presidential campaign today, saying to a conference of the Women’s Leadership Forum that “the Republican agenda sets back women’s rights and I pledge all my energy towards a big 2016 victory for Democrats across the country.” Chafee was getting no traction in national or Iowa polls of Democrats, nor did he perform well in last week’s televised debate.

With Vice President Joe Biden ruling out a third presidential bid and Jim Webb ending his quest for the Democratic nomination this week, the primaries are shaping up to be a straightforward choice between Hillary Clinton and Bernie Sanders. Martin O’Malley won’t have to fight with other second-tier candidates for attention anymore, but he has a lot of work to do to present himself as a viable alternative to the front-runners.

Chafee had been scheduled to speak last at tomorrow night’s Jefferson-Jackson dinner in Des Moines, and I was dreading the prospect of hundreds of people leaving the hall during his remarks. Way too many Iowa Democrats did that during Chafee’s speech to the “Wing Ding” in August and during Webb’s speech to the IDP’s Hall of Fame dinner in July. Such poor form not to hear out all the candidates, even marginal ones.
