Liberal revenge

Liberals seek revenge on members of their own party for speaking out against their agenda, instead of of listening they just double down and engage in political attacks.
Could you potentially see a shift if the left gets smart and see possibly a RFK - fetterman presidential ticket in 2028? . I don’t think that the Democratic party will learn but we will see as that ticket could be their rebound saying we learned our lesson, it is time we listen to the people.
