There are a couple of problems with that argument
1) You are wrong when you say "Bernie is a my way or the highway type". You are just making that up. Look at his record in Congress... he worked with Republicans.
You are wrong about Bernie's followers. I don't dismiss Congress, and I do accept the facts as they are. Accepting the facts as they are doesn't mean giving up, it means taking them as a starting point.
2) You are wrong about Bill Clinton's record (with Hillary's support).
Bill Clinton didn't just "accept the facts as they were"... in many cases he actively made things worse
for political capital. Among these cases I would include.
1) The Defence of Marriage Act signed into law by Bill Clinton, and the Don't Ask don't tell policy. These Clinton policies held LGBT rights back for decades.
2) The "End of Welfare as you know it" policies hurt minorities and force mental ill patients on the street. Bill Clinton campaigned on this... and it hurt us as a country.
3) The tough on Crime bills enacted by Bill Clinton and trumpeted by then First Lady Hillary ended up swelling prison populations and targeted largely minority communities.
We are still feeling the consequences of these bill today.
There is a difference between "pragmatism" and political gamesmanship... you can have both pragmatism and principle. The last Clinton administration didn't govern that way, and there is no reason to think the next on will.
