So far, zero response from McCaskill on what specifically she means by public option, as I’ve asked before. However, she did tweet yesterday a clue to her thinking on the role of a public option in our health insurance system.

Big mistake, tweetng when dead tired,one more time spelled right….I support public option,as long as private can compete. Now sleep.
