Among Democrats, far left is only electable in certain regions. Moderates in other regions. They need to work together to have a majority.

Unfortunately, I doubt the majority of people, in this country, would support candidates considered to the far left. The left has traction in cities like New York and Seattle. Maybe even in Bellingham. Not across much of rural USA.

I think a "big tent strategy" is needed for the Democratic Party. One size fits all doesn't work and just leads to internal strife in any party. Different regions should support and elect who their voters wish. A diversity of opinions and strategies should be able to function and find at least some measure of consensus upon civil discussion.

Power to the people also means to the people who think in a great diversity of ways.
