Do the left need another think tank?

Although Owen Jones is stating he doesn't want to start a new political party, and I do believe him, he is, however, wanting to start a new left-wing think-tank.

Surely there are enough think-tanks for people to turn to Owen such as:

The Fabian Society
Institute for Public Policy Research
Demos
Compass- Direction for the Democratic Left

These are just a few, I'm sure there are more think tanks our there that are just as useful for people.

But there aren't  just think tanks, but  smaller politcal parties, if Labour aren't doing or saying what you would like them to, to turn to:

SWP
The Green Party
The Liberal Democrats (Although we can all speculate there)
Respect Party
Social Democratic and Labour Party

Then there are blog sites:

Left Foot Forward
Liberal Conspiracy
Next Left
Labour Uncut
Progree Online
Young Fabians Blog
The Green Benches
Penny Red

I could go on, and on, and on.

Then of course you have the Unions, if you feel you need to back up whether it be for political reasons or legal reasons, they are there:

TUC
Association of Flight Attendants
Musician Union
EQUITY
National Union of Teachers
NUJ
UNISON
VOICE

There are a lot of voices on the left, I've only mentioned a few here, do they really need another voice, shouting out, trying to 'unite' the left together?

I can see what he's trying to do, he is a brilliant PR spokes person for Labour, he's trying to get all of the left back on Labour again, but sadly, no amount of think tanks, and blog sites, and Unions will change the faces of Labour: Ed Miliband, Ed Balls, Harriet Harman, all three people that we, the general public, lost faith in after 13 years of absolute dishonesty, and power.
