There may be more data later today.
Given what is there, I feel comfortable in saying that Clinton will win PA by someplace in double digits, as she will comfortably (perhaps close to 30 pt margin) win MD and comfortably (perhaps 15-20 point margin) win Delaware. I think she wins CT and margin is 10 =/-3. My gut is that she ekes out a win in RI, but by <5 and possibly <2. Here it depends: will independents decide it is more important to go mess with Repubs by voting for or anti- Trump rather than vote for Sanders?
Delegate margins? It depends on Penna. As of right now I feel comfortable in saying that Clinton will net at least 50 delegates — perhaps 39 just from MD. If the margin in Penna goes to 20 points it is not inconceivable she could net 80.
RI, regardless who wins, will be 13-11, 12-12, or 11-13. No one is going to gain much.
Make of this what you will.
