I hope Bernie Sanders starts his People's Party.
He needs a platform from which he can launch his socialist ideas.
He also will attract other sophisticated socialists from the democrat party.
This will 'purify' the democrat party, allowing it to 'resize', to accommodate the traditional 'conservative opposition'.
I'm conservative, and would love to see a three of four party system.
The panoply of political ideas, can't be achieved by two parties.
