A lot of my friends and colleagues — and political journalists and bloggers — have spent a good chunk of time this week debating whether or not Barack Obama is "shifting to the middle," or how much he is shifting, or whether it's politically necessary or smart or disastrous for him to do so. You and I might not answer those questions the same way, and could probably have great discussion over dinner or drinks.
But I've been thinking more about a different set of questions. What should we expect -- or demand -- from progressive candidates in an election year? How can we most effectively advance our principles and mobilize our supporters to make a difference in these important public debates?
