Sanders lambasts Dem Party strategy

At the People's Summit in Chicago Sanders called the Dem Party's current direction "an absolute failure." He praised progressives for making some inroads into the Party platform but overall the Party is obstructing further progress. 

“The Democratic party needs fundamental change. What it needs is to open up its doors to working people, and young people, and older people who are prepared to fight for social and economic justice.
The Democratic party must understand what side it is on. And that cannot be the side of Wall Street, or the fossil fuel industry, or the drug companies.”

It's encouraging to see organizations training and encouraging progressives to get active in politics. And supporting them when they run for office, even challenging establishment Dems in primaries. But ultimately progressives must unite their coalitions and dump the Party, because it isn't going to ever change back to a People's Party.
