The anti-war left is not going to abstain from voting for Mrs. Bill Clinton. They certainly did not abstain from voting for "moderate" Democrats in 2006 either. While they may whine loudly at the Democrat party for not cutting off funding for the war, they won't abandon Democrat party candidates at the polls.
Richardson is not needed as long as the Republican candidate takes a strong stand against illegal immigration.
I'm not quite sure how you make this connection. I think a lot of Hispanics who have never voted would be drawn strongly to a Clinton/Richardson ticket simply because Richardson is Hispanic.
Don't be so sure. There is an uprising building among the Dems.
Putting Obama on the ticket precludes a strong anti-war third-party candidate from siphoning votes away from Clinton.
