It means that anyone who has ideas that resemble the tenets of communism, socialism, marxism, etc. don't have a political party that pushes for these ideas. Both the leader of the Democratic party (Biden at the moment) and the leader of the Republican party (still Trump) lash out at socialism every chance they get. Even Bernie Sanders, who both sides of the aisle would label a "socialist", is pushing hard for a $15 minimum wage, something socialists would call a cop-op compromise with capitalists. We don't want a minimum wage dictated by the federal government, we want democracy in the workplace so we can vote on our own wage. Even AOC, who the right believe is socialism incarnate, pushes her "Green New Deal" which seems to be a response to climate change that does its best to accommodate capitalists.
