Depends on the definition of "good Democrat", like said above. Today you're only "good" if you're "evolved" on abortion, gay marriage, weak US defense, kooky environmentalism, affirmative action, etc. Time was you could find a lot of conservative dems. Now they're as rare as hen's teeth.
Heck Jimmah in 1976 was pretty conservative at least socially. But he's "evolved" into an anti-American modern liberal nutball.
