Which leftist politicians

How about Chris Dodd and Barney Frank who short-sold before the 2008 crash? Or Nancy Pelosi that snider trading, Jamaal Bowman pulling a fire alarm to stop a vote he knew he couldn’t win?

What does a leftist believe in to you

Government control and central planning, less individualism and more government involvement in personal affairs, a general curtailing of liberty and having a paternalistic involvement to provide for people who should provide for themselves.

I'm a leftist and I believe in no central government or planning. I believe in decentralized organization. I believe in community and cooperation. I also believe the local community should own the means of production. I also believe everyone should get what they need.

Perhaps someday you will be wiser also.
