I agree, which is why John Fetterman is able to see and understand the democratic party has lost the values of what his Party once stood for.

This is ever true, and it is ever true for both parties.

Parties are political coalitions, they change and evolve over time, and they always will end up standing for different "values" than they used to. MAGA would be anathema to Reagan-era Republicans (much less the Rockefeller Republicans who preceded them), and the modern Democratic party would be unrecognizable to the Kennedy-era Dixiecrat/rural voters that held great sway back then. Neither political party does, or ever will, hew to the values of three generations prior. Just not how the world works.

It is also ever a popular game for partisans to find the member(s) of the opposing party who come closest to their own very different political views, and extol them as having wisdom and vision that the rest of that opposing party lacks. Democrats praise the never-Trumpers, while Republicans praise whoever is criticizing the Democratic far left (be it a Manchin or Fetterman). It lets those partisans feel validated and supported. "See, even [MEMBER OF OPPOSING PARTY] agrees that [OPPOSING PARTY] has gone too far in rejecting my eminently sensible opinions!" But it doesn't really mean anything. Again, parties are political coalitions. There will always be members in the party on one far side of the political spectrum within the party who reject the positions of the faction on the other side of the political spectrum.
