Despite having been a Republican more recently, he's certainly more of a Democrat than Clinton. If O'Malley or Sanders don't work out, Chafee is a good backup candidate, since his positions on the issues are better than Webb's.
Lincoln Chaffee, who voted for the Bush Tax Cuts and wanted to privatize Social Security, is more of a Democrat than Hillary Clinton and a good candidate for jfern. What a principled a progressive!
Don't forget his vote for Trent Lott as Senate Majority Leader.
Criticizing him for that? Talk about nitpicking...
