Operation Chaos was about supporting the weaker candidate (Hillary Clinton against Barack Obama in 2008) in order to prolong the conflict within the Democrat Party for as long as possible. The analogous candidate in this primary season is clearly Joe Biden. He is the least popular, most damaged candidate and would be the easiest for President Trump to defeat. His success would also do the most to maintain the 'socialist verses communist' battle within the Democrat Party. It would also keep Michael Bloomberg at bay. Voting Joe Biden is the clear Operation Chaos choice.
That said, it sounds as though from your post that you are actually a Yang operative trying to buoy his failing candidacy by duping gullible Republicans. If Yang wants our vote, he should change parties and drop the forced cash redistribution shtick. He would have a much better chance getting elected to any political office as a Republican that we would as an "oppressor class" Democrat in their world of identity politics.
