New Mexico Gov. Bill Richardson dropped out of the race for the Democratic presidential nomination today, after tanking in the Iowa caucuses and the New Hampshire primary. In making his announcement, he looked on the bright side: “A year ago … we were the campaign with the most aggressive clean energy plan and the most ambitious standards for reducing global warming. Now, all of the remaining candidates are coming to our point of view.” Richardson, a former secretary of energy, did indeed have a big, bold climate and energy plan, and he (along with John Edwards) inspired the other Democratic candidates to introduce ambitious plans of their own. Richardson says he won’t yet endorse another candidate. For more on Richardson, check out Grist’s interview with him and fact sheet on his platform and record.
