After voting for the Democratic Party for 28 years, I walked away from the party for the GOOD of the American public. Unless and until the Democratic Party returns to its roots as the party for the working class, it will not serve the American public well.

And, no one in their right mind blames Sanders for Clinton's election loss. She was a poor candidate. The DNC was warned of that fact even as it rigged the primary in her favor with its limited debates, Super Delegates (who made a decision even before Clinton had a challenger) and use reporters sympathetic to Clinton to tar Sanders. Clinton lost because she lost the Rust Belt, which hated her trade policies.

Sanders is very popular with black youth, who will influence their elders in 2020 after having been correct about Clinton in 2016.

You and others in the party should realize that many former Democrats will no longer vote for anymore centrist neoliberals the elite put up, no matter their gender or race. Lesser evilism is over.
