Do we need a "People's Lobby" as a first step towards creating a new political party?

A thought from Podunk:

We need to break free from this two-party trap by establishing a working class based progressive people's party for peace, social and economic justice in this country if we want any significant change.

Perhaps a good first step towards political independence would be if we united liberals, progressives and the left in some kind of "people's lobby" for peace, social and economic justice behind a program and platform for ending these dirty imperialist wars and using the resulting peace dividends to finance real health care reform where we would see single-payer as a first step towards a national public health care system which would create some three-million new jobs right off the bat with another ten-million jobs down the road, making full employment a legislative mandate, create a national child care system, defend and expand Social Security, protect and defend Mother Nature.

What do you think?
