In the letter he attached, he concluded with something vague that I think could be hinting at announcing a new third party or him moving to an existing third party. I like that Jason Hickel and Shaun have pointed out this could be the moment to start the difficult fight of replacing dems with a different party, and tbh demsocs might be the ones to do it.

This could actually work and get traction, and it would absolutely end the democratic party, who no longer has a constituency
