Who do you think will replace Elizabeth Warren on that committee that she is so perfect for,
and will that person do anywhere near what she is capable of?
Or will that person be like any other person was all prior years?

It is an important question to ask, if she has to spend 3 years running for President.
(and as or if she is following in Hillary's footsteps, I personally do not see her running if Hillary runs.)
VP maybe, but doubtful as she is perfect for the role she is playing.

IMHO.

Lynch is running to win, and if he doesn't, for Gov.

2017.
Lets just hope Warren-D does not leave the US Senate.
2014
Democrats will have a Primary for Governor.
US Congress- Capuano-D vs Lynch-D
Statewide Office- Grossman-D vs Bump-D.
If Lynch-D wins the Special, Progressive Democrats can focus on winning Lynch's former US House Seat with a more progressive candidate. In 2014 Democrats could recruit a high profile Progressive to challenge Lynch-D in the Democratic Primary.

There is no one more suited for her particular job, and she can end up one of the great Senators of all time.

Keep up the good analysis of all the races,as said, been reading all of them, and don't know if I commented before, so wanted to tell you.

Lieberman.

MA has a progressive Democrat that is a leader of progressive issues at the national level- Liz Warren.
Blue Collar Social Conservative Democrats could get Representation in the US Senate if Lynch becomes US Senate.
Ed Markey-D remains in the US House based on his seniority status- number 8 and if Democrats regain control of the US House- chairs the Natural Resources committee.
