Tulsi Gabbard addresses the attacks she gotten for denouncing corporate money and going against Democratic establishment, & explains why she still is a Democrat.
A third party, a Progressive Party, would split both the Democratic and Republican Parties. It would put the Progressive Party's candidate in the Presidential debates because that candidate would do better than 15% in national polling. There would also be coattails at the state and local levels to reinforce the efforts of progressives already running and winning even now in some cases.
The hardest part about forming a Progressive Party would be sticking to the truth no matter how angry it makes the libertarians, neocons, and so-called liberal interventionists.
Bernie Sanders could not lead that Progressive Party because he doesn't actually believe in sticking to the truth. He's soft on lies. We can't have that. He's a lesser-of-evils person rather than an uncompromising progressive on both domestic policies and practices and international affairs. He didn't stand up to the Clinton-corporate Democrats. He only pays some lip service concerning the Palestinians right of return. He echoes the nonsense about Russia and Putin.
Tulsi Gabbard is better than Bernie Sanders, but she's not going to rally the youth for starting and moving a Progressive Party the likes of which the USA has never seen.
If I didn't hate the system so much, the system in which the Progressive Party would have to run, I'd run for office myself on a platform of pure truth forever. Would anybody even hear me? Is anybody even listening now?
